(Callback DB_KeyB_CB) The 6 pages for setting the DAS working parameters are showed.

Parameters

Page 1

The section Equipment Type of the page Parameters allows for the coiche of different instruments that can be managed by DAS:

SPATRAM (SPectrometer for Atmospheric TRAcers measurements) - CGE-UE
SPATRAM2 (SPectrometer for Atmospheric TRAcers measurements v. 2) CGE-UE
SPATRAM3 (SPectrometer for Atmospheric TRAcers measurements v. 3) CGE-UE
TROPOGAS (TROPOspheric GAScod) ....
LIS (Lampedusa Island Spectrometer) ENEA
GASCODNG1 (Gas Analyzer Spectrometer Correlating Optical Differences New Generation 1) CNR-ISAC
GASCODNG2 (Gas Analyzer Spectrometer Correlating Optical Differences New Generation 2) CNR-ISAC
GASCODNG3 (Gas Analyzer Spectrometer Correlating Optical Differences New Generation 3) CNR-ISAC
GASCODNG4 (Gas Analyzer Spectrometer Correlating Optical Differences New Generation 4) CNR-ISAC

The selection of the new instrument is stored in the "..\DASxxx\Config\Equipment.ini" file, but to make effective the new setting the DAS has to be re-started
The section CCD & OMU Temp allows for the modification of the target temperature and power assigned to the Peltiers for the OMU as for the CCD Camera

CCD target temperature
CCD Init Peltier Power
OMU target temperature
OMU Init Peltier Power

The section CCD Window allows for the choice of the CCD windows used and the setting of the vertical binning

CCD window
CCD vertical binning

The CCD Setup Button execute the DCS tool to select and setup the CCD Camera and Controller.
The Apply button (Callback ApplyChCB) has 2 different functions:

If the CCD Setup has been executed copy the 'camera.cfg' file to the "..\DASxxx\config\'Equipment'\dcs" directory, init the camera (DB_InitCamera) reading the new configuration files and applies the new settings for the current session
If the CCD Setup has NOT been executed init the camera (DB_InitCamera) reading the old configuration files and applies the new settings for the current session

The Store button (Callback WriteParaminiCB) has 2 different behaviours if the CCD Setup has been executed or not:

If the CCD Setup has been executed copy the 'camera.cfg' file to the "..\DASxxx\config\'Equipment'\dcs" directory and write the new parameters in the file "..\DASxxx\Config\'equipment'\PARAM.INI",
if the CCD Setup has not been executed write the new parameters in the file "..\DASxxx\Config\'equipment'\PARAM.INI",

.
At the next DAS execution the new setting will be loaded.
The Close button (Callback CloseConfigCB) close the DAS_Config Window

CCD Setup

The 'dcs' tool (DTA Camera Select-Setup) ,by default, read and write the 'camera.cfg' and 'dcl.cfg' in the ..\DASxxx\dcl directory and allows for the selection of the used platform (Page 'Platform')

DCS Platform

Allow for the selection of the CCD controller:

HiresIV for SPATRAMPLUS, GASCODNG1,2,3, TROPOGAS and LIS)
HiresV for SPATRAM2, GASCODNG4

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 DAS314 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 DAS315 and following, the Central wavelength and the steps can be modified In addition using the function Lookfor4358, 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,
2 more spectral window can be added in the UV region for example (2823, 3132, 3337, 3650, 3850).
This can be obtained

using the above graphic interface
modifying directly the 'wlstep.ini' file in the equipment config directory

NOTE - the 435.8 has to have step = 0 and the steps towards the UV must be negative (towards the visible positive)

                SECTION OPTIONS ********************************

Options

The Options Panel has 7 sub-pages:

Almost all the options can be changed during the execution of the program in real time, so there is not a button applying the modification (as in the parameters page). The new settings are applied immediatly and will be lost at the end of the session. In order to mantain the modified settings also for futures runs of the program the button Store has to be used.

+++++++++++++++++++++++++ SECTION OPTION PAGE 1 +++++++++++++++++++++++++++

Options - Page 1

The first page allows for setting some options regarding mainly spectra and file storage (see below)
Section Saving Options
Saving mode

ASCII: Spectra are saved in ASCII mode
Binary: the binary mode save space on the disk (the best choice!!!)
File names

Free: DAS asks for the name of the file where the spectrum will be saved.

Automatic: DAS assigns to the file names the format AAAYYMMDDxxx.ext
where:
- AAA = Name of the station (in the file "Path\DAS\Config\GeoCoord.ini")
- YY = year
- MM = month
- DD = day
- xxx = progressive number (0,1,....999).
- ext = bif or dat, according with the Spectra Saving Mode.
  Each file will contain 50 spectra
  
  Type of image
Mono: Fixed
RGB: The RGB mode is reserved for future realise.
Section Averaging
Automatic AutoRange for AVG: Selecting "YES", when the averaging button is pushed (or the E_AVERAGE or the E_AVGCCDHor procedures) the Autoranging procedure is executed in order to set the Integration Time -TExp- utilized for the Averaging. Selecting "NO" as Exposure time the last Integration time used it will be utilized for the averaged measurements. ( The "Average" button is equivalent to the "GetCCD" one where the ARange button has to be used before the measurements )
Fixed Exposure Time or Fixed Number of measurements (In order to obtain highest S/N ratio
Fixed Exposure Time: the text box below report the total time over wich the measurements will be performed
Fixed Number of measurements the text box below report the total number of measurements that will be performed for each scan

The Defective Pixel Section take into account that during the life of the instrument the CCD sensor can degrade his performances. In this regard the 2 push buttons Map UNDER Exposed pixels and Map OVER Exposed pixels can give the maps of the defective pixel. Defective pixel correction

DISABLED ( in this case no correction is applied to the CCD Image) or
ENABLED (the CCD image is corrected with a cubic spline interpolation over the defective pixels listed in the file "Path\DAS\Config\ccd_defect_Danbo.cor".
The Save Button writes the new settings in the "...\DASxxx\Config\'Equipment'\Options.ini" file
The Close Button close the DAS_Config window

Options - Page 2

The second page allows for setting some options regarding mainly CCD Dark removal, CCD Target temperature and System files (see below)
Remove dark from measurements

Yes –> The dark is removed from the measurements
No –> The dark is NOT removed from the measurements Dark source
Full Frame –> if the previous option is estted on "Yes",the dark is removed from the measurements and rhe source is the full sensitive area of the CCD sensor (this means that a DARK measurement is carried out before the LIGHT measurement).
Blind Pixels –> if the previous option is estted on "Yes",the dark is removed from the measurements and rhe source are the 30 Blind Pixels on the right of the CCD sensor (this means that the DARK measurement is not necessary).

CCD Target Temperature

Fixed –> The CCD target temperature remains always that is setted in the Parameters page
SZA Driven –> The CCD target temperature varies with the Solar Zenith Angle. The temperature starts decreasing when the SZA is higher tham 80�

Config Files

5 of the 6 buttons can be used for the editing of the configuration files for DAS:
The last button is a free editor

Hidden lines
The CCD sensor could be not homogeneously illuminated, so some lines could present a mean value too low and if all the line are plotted could not be possible to appreciate the quality of the measurement. Depending on the vertical binning, the numbers of lines to be plotted, after and before the central one, can be selected.

Before Central Line
After Central Line

Display Blind Pixel?
The CCD sensor in use (Marconi CCD3011-Bi) has 1054x256 pixels, but only 1024 are illuminated; the remaining 30 are blind and can bu used for the quantification of the read current
