Until DAS306 the spectral windows were fixed and only with source code modifications should be possible to modify the Central Wavelength/steps and consequently the spectral windows of measurements.
Starting from DAS307 to DAS315 it is possible to modify the number of steps, but not the Central Wavelengths.
Moreover the Reference Position (4358 A, step = 0, with ID = 3) is fixed, forcing to have only 3 more window in the UV (2823, 3337, 3850).
With DAS316 and following, the Central wavelength and the steps can be modified In addition using the function LookforWl_X, it is now possible to assign the reference position 435.8 nm to any ID. If the reference position 4358 A, step = 0 has ID = 5,
I can Add 2 more spectral window in the UV region for example (2823, 3132, 3337, 3650, 3850).
This can be obtained:

using the graphic interface in "Config–>Parameter–>Page 2
modifying directly the wlstep file in the equipment config directory
- with a standard text editor
- with the embedded MGUI text editor in "Config–>Options–>Options - Page 2

After these modifications the windows for the wavelength positioning will be:

Note the presence of the 2 new spectral windows centered in the 3132 and 3650A.

NOTE 1 - the 435.8 has to have step = 0 and the steps towards the UV must be negative (towards the visible positive)
NOTE 2 - The step values listed in the wlstep file, are NOT the real steps executed by the grating stepper motors, since the steps have been parametrized in order to allow for the modification of the motor settings (AMS Steps/round) without any change in the wlstep file. The parametrization take into account the capabilities of the AMS2 (Advanced Micro Stepping) Controller to apply the microstepping technology. The DAS encoding procedure is located in the SD_Grating function. Also the mechanical reduction (mr=4) of the grating positioning device is taken into account.
In practice:

$StepsExec(t(i)) = StepF * (AMS_StepR(t(i))/3200)* mr$

with:

= Fractioning of the motor stepping (microsteps) for i =0,1,...13. (AMS Steps/round);
= Steps executed by the stepper motor;
= Steps read in the wlstep.ini file;
=AMS Steps/round = (200 step/round is the nominal value for a standard stepper motor);
= mechanical reduction = 4;
= Normalisation Factor (NormFac);

In the table below is reported an example with StepF = 12180 as read in the wlsteps.ini file

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Arange

The autoranging procedure is one of the most important DAS's functions since it calculate the optimum exposure time for the measurements in order to:

obtain the highest SNR ( for situation with low energy of the incident radiation )
prevent the CCD satuaration ( for situation with high flux of radiation.

The autoranging procedure can calculate the optimal exposure time with or without the shutter installed.
With the Shutter system installed and until realise 3.1.5 the Exposure Time (TExp) is calculated with a very simple and empirical formula:

$TExp = \frac{LEVEL * TExpAR} {Max(TExpAR) - Min(TExpAR)}$

with:

LEVEL = Maximum Target of the measurement (usually 55000 Digital Counts)
TExpAR = Exposure time of autoranging used to carry out the test measurement (= 0.1 s)
Max(TExpAR) = Maximum value of the Test Measurement
Min(TExpAR) = Minimum value of the Test Measurement

The previous expression is valid mainly for measurements of spectral lamp radiation where the the difference between Max and Min is very high due to the presence of the spectral lines. For measurements of scattered solar radiation and for the different offsets of the CCDs Equipping the Instrument maneged with DAS, additional terms has to be sometimes added or subtracted to the previous equation.
The procedure can be summarized with:
After the first measurement with the TExpAR exposure time, the obtained signal is checked:

if Max(TExpAR) > LEVEL then DAS enter a DO cicle decreasing the TExpAR until when it is lower than the Minimum Exposure time (TExpMin) allowed
- If TExpAR <= TExpMin then the Neutral Density (ND - usually ND2) filter is positioned for the test measurement
if Max(TExpAR) < LEVELINF (LEVELINF = 4000 digital counts) then DAS enter a DO cicle increasing the TExpAR until when the LEVELINF is reached in order to be sure to measure something. Actually this DO cycle is repeated 4 or 5 times for a TExpAR maximum of about 5 s

If the shutter is not installed the minimum exposure time depends on the CCD Reading Time (RT). This last is function of the binning parameters and for the HIRES_IV CCD driver, it can be calculated according to the formula:

$RT = \frac{vp}{vb}�Kv + \frac{vp}{vb}�\frac{hp}{hb}�Kh$

where:

RT = reading time (in ms)
vp = vertical pixels number
vb = vertical binning
Kv = 0.024 for hires
hp = horizontal pixels number
hb = horizontal binning
Kh = 0.0125

For High values of Vertical Binning RT is very short (i.e for VertBin of41-the maximum supported by HiRESIV-RT is less than 0.09 sec) therefore the excess of signal due to the over-exposition of the sensor can be neglected.
Therefore, for measurements without the shutter installed, the minimum exposure time (TEexpMin ) allowed is depending mainly on the vertical binning and on the radiatin flux. The TExpMin is fixed as the double of the RT

$TExpMin = 2 * (\frac{vp}{vb}�Kv + \frac{vp}{vb}�\frac{hp}{hb}�Kh)$

This approach is still under testing phase, so to obtain the best results it is still advisable the use of the equipment with the shutter installed.
One of the factors manly affecting the autoranging procedure is the type of shutter used to carry out the spectral measurements. At the beginning of the equipment development the Uniblitz mod.:VS25 shuttering system was adopted. This is a very fast system (the opening and closing phases of about 5ms each one) allowing for the neglection of the influence of the signal received by the CCD during the transient periods. The main problem with the VS25 is the limitation of 1.000.000 (un million) of ensured shuts. Taking into account the high frequency of the measurements, (the one million of shuts are reached in 2 months of instrument 12h operation) it was necessary to change the shuttering system.
Two new shutter systems were developed:

The rotating shutter - ROTSHUT - based on a rotating wheel with 4 equi-spatied holes actuated with a stepper motor driven by a SSC controller. This system is slower than the VS25 (45ms against the 5ms of the VS25), but more durable. the main disadvantage of this model is the increased number of wirings to be set-up in the monocromator and in the ECU.
The flagging shutter - TORQUEM - based on a torque motor acting on a flag. This is simpler than the ROTSHUT (the TORQUEM use the same wiring of the VS25), but it's not still fully tested (07/02/2011)

The studies on the capabilities and on the behaviour of the VS25 and ROTSHUT systems suggested the implementation of a new Autoranging procedure. The procedure implemented and used starting from DAS 3.1.6, is based on the linearity of the CCD charge with exposure time according to the formula:

$Y = m�X$

where:

Y = CCD Signal (digital counts)
m = slope
X = Exposure Time (TExp)

since m is:

$m = \frac{Y2 - Y1}{X2 - X1}$

the exposure time TExp can be calculated according to the formula:

$TExp = LEVEL �\frac{TExpAR - TExpMin}{Max(TExpAR) - Max(TExpMin)}$

where:

LEVEL = Maximum Target of the measurement (digital counts)
TExpAR = Autoranging time (X2)
TExpMin = Minimum Exposure Time (X1)
Max(TExpAR) = Maximum signal obtained for Autoranging Exposure time (Y2)
Max(TExpMin) = Maximum signal obtained for Minimum Exposure Time (Y1)

The new autoranging procedure (adopted for DAS316 ) can be summarized with:

the first measurements is performed with the TExpMin
If Max(TExpMin) > LEVEL then the Neutral Density filter is positioned
- The measurement with TExpMin is repeated and the 'zero' value is determined
A measurement with a fixed TExpAR time is carried out
- If Max(TExpAR) > LEVEL then DAS enter a DO cicle decreasing the TExpAR until when it is minimum the double of TExpMin
- if again Max(TExpAR) > LEVEL then the Neutral Density filter is positioned if not already present
the whole procedure is repeated
if Max(TExpAR) < LEVELINF (LEVELINF = 4000 digital counts) then DAS enter a DO cicle increasing the TExpAR until when the LEVELINF is reached in order to be sure to measure something. Actually this DO cycle is repeated 4 or 5 times for a TExpAR maximum of about 5 s
The TExp is calculated
Some additional controls checking the validity of the calculate exposure time are performed

Automatic Autoranging

Yes: the autoranging is performed before the measurement and the calculated exposure time value is used for all the measurements.
No: the autoranging is NOT performed so the last autoranging time or the specified one (in case of automatic measurements) is used. If the exposure time is zero (if DAS is just initiated and no measurement is carried out yet) the user is awared of this situation and the procedure is interrupted.

Fix TExp: the measurements are averaged since the Total TExp setted in the edit field is reached (the number of measurements is automatically calculated

3.1.6 - 26/04/2011 - DAS Main revision - First version with the new dclrefman (ver. 5.64) allowing for the use of the HiresV CCD driver with USB2 Interface. The old libraries files (dll and lib) were replaced with the new ones (dcl.dll, dcl.lib, qt-mt338.dll,mfc90.dll, msvcr90.dll, msvcp90.dll, msvcr80.dll, CCDPlugDTA.dll, dcolib.lib, FTD2XX.dll). In addition the new DTA Camera Select tools ver. 1.2.8 (dcs.exe) has been adopted.
In DAS316 and following version, even if the new dclrefman (ver. 5.64) are compatible with the old ones some main modifications were required to the code and to the DAS File System (fs).
Regarding the fs, the 'dcs.exe' application that has to be placed in the DAS root directory "...\DASxxx" with the 'dcl' subdirectory containing the files:
- 'camera.cfg' - the camera configuration file. By this file, you can set the camera model, the sensor type, the interface type and so on, with regards the CCD camera you are using.
- 'dcl.cfg' - the file contains all the definitions about hardware platforms (data of to the DTA cooled digital CCD cameras)
- 'eia1956.raw' -.raw file (optionally present) is that generating the images in case one uses the program in demo mode.
- help - file containing all the helps necessary to explain the commands of the 'dcs' program.
- fdlusb.dll - library for the USB2 cameras
'dcs.exe' by default, load the configurations files ('camera.cfg' and 'dcl.cfg') contained in 'dcl' folder.
DAS instead load the "'equipment'.cfg" file contained in the "...\DASxxx\Config\'equipment'\" subfolder and 'dcl.cfg' contained in 'dcl' folder. Please refer to CCD Setup for a full explanation on how DAS use 'dcs.exe'
Multiple bugs were fixed and new functions added:
- The adoption of a new CPU platform (NOVA945GSE instead of the NOVA7892) required the addition of new procedures for the access of the SUPER I/O ..... required for the use of some facilities (mainly I/O ports and WatchDogTimer - WDT).
- In the DAS Config Panel, page Motors, a new page (SET NOVA MB) is present allowing for:
  - the selection of the installed motherboard,
  - the check of the output and input ports of the selected motherboard,
  - the setting and test of the Watch Dog Timer.
- New syntax for the PRG file is adopted (PRG Commands)
- The check of the PRG file syntax is performed when:
  - DAS is executed in one of the automatic modes (Automatic and Unattended Mode)
  - or in Manual Mode through the Compile PRG button in the Tools keyBoard.
- New Autoranging procedure is implemented (Arange)
- In order to prevent DAS crashing, a new function is introduced (ChkWinInstance) checking if some windows are already created pressing one of the keyboard buttons (Namely this feature affects the 'DAS Config', the 'MOVE GRATING' and 'DAS TOOLS' windows).
- New function EquipCode2Name Translating the Equipment Code in the Equipment Name (useful also for future use i.e. translation of errors codes).
- Revised the DB_ScanMaxMin procedure: now the scanning for Max and Min of the image is done only on the sensitive pixels.
- Modified DB_GetCCD for the new HiresV CCD Drivers: actually only for SPATRAM2 instrument!!!!
- Fixed bug in D_Average procedure: if the automatic Autoranging option () is not setted and TExp = 0, DAS can't perform averaged measurements.
- Fixed bug in the time of measurements: if the daylight saving time flag (tm_isdst) is active (>0) the procedure gettime subtracts 1 hour to the PC time. Therefore the time stored in the header of the measurements is always the Local Solar Time (LST) and the user doesn't have to be warried about the daylight saving time setting on the equipment.
- Added the ERR_Option procedure, to be used after the LoadDB_Options function.
- In the LoadDB_Options added some lines of code allowing for the detection of a wrong lenght of the file. The user is warned if this happen.
- Added controls reporting errors for system files during DAS boot (DAS System Files)
- Added controls reporting the exixtence of the "...\DASxxx\Data" and "...\DASxxx\LOG" folders. If the folders do not exist, they are created (LoadSetDirs)
- Added in Task_CCD_Temp the code accounting for the use of a standard UPS connected throug COM or USB port, in order to avoid thermal shocs to the CCD since the working temperature of the sensor usually is of -35�C. The shutdown is realized when the OS enter in the battery operation mode, and DAS provides the CCD shutdown. In addition also the equipment thermoregulation is suspended. The control is obtained thanks to the GetSystemPowerStatus windows function.
- Added functions for WDT management for the different boards (NOVA7892 and NOVA945):
  - Shared: TaskWDT and WDTRefresh
  - NOVA7892: InByteR....
  - NOVA945: ISMM_Open, ISMM_Close, WDT_SetTimeout, WDT_Start
- Added code and callbacks for NOVA Input ports (NOVA_In, NOVAIn_CB)
- Fixed bug in the plot visualization time. When DAS execution, started in AUTOMATIC mode, is changed to MANUAL, with the splash window created at DAS boot, the plot was shown only for 4 sec. Now the plot window remains active till when the user decide to close it.
- Restored the pixel correction procedure - ccd_defect_danbo.cor - (for GASCODNG2 mounting CCD3011Bi (Ex-Evora)). New control in DAS Configuration Panel - Options - Page 1 allowing for the selection of a new CCD correction archive (that must be in the "\config\'equipment'" folder.
- New encoding for the MIGE positioning. Azimuth range: 0-360, Zenith range 0-180. NOTE - for the Zenith axis now the elevation has to be considered (i.e. ZENITH 20 means 20 deg of elevation)
- 10/05/2011 - New syntax for AAMEASURE and AAPOSIT keywords (PRG Commands). DO NOT USE the keywords AZIMUTH and ZENITH in PRG files.
- 14/05/2011 - Fixed bug in the plot repetition. When the option 'Display Plot After Measurement' (in DAS Configuration Panel - Options - Page 3) was set to 'YES', depending on the memory availability, after about 2 hours, DAS stop the execution due to a low amount of physical memory. This beavhiour was caused by the re-initialization of the Image plotting the spectrum. Adding the istruction MFreeImage() in the ClosePlotCB() procedure the problem was solved, now the plot visualization option can be set to 'yes' in automatic mode execution.
- 17/05/2011 - Fixed bug occuring when the *.prg file is loaded through the TOOLS keyboard. DAS Working directory and MGUI Environment (SetWorkDirMGUIenv) were lost.
- 18/05/2011 - Fixed bug in the writing of the xxxyymmdd.log file: now the procedure use the last value for the CCD temperature directly from the DAS.Marconi.CCDTemp data field (Task_LOG)
- 20/05/2011 - Fixed bug in the 'Temp History' button. When the log file is plotted the env variable is loss. Problem soved adding the SetWorkDirMGUIenv() function at the creation of the plot shell.
- Fixed bug in the right click of the "Save As" button in the PLOT window
- 12/09/2011 - modified the autorange function:
  - the 'lowval' parameter is fixed to 1000 in order to reduce the autoranging attempts.
  - the zero point measurement is performed by the SPATRAM2, GASCODNG1, NG2, NG3
  - for GASCODNG1,NG2,NG3 if the measurement at 435.8 nm blooms the CCD, depending on the previous band pass filter position, DAS positions the band pass filter with the ND filter (B12–>B12F, B39–>B39F
