DBSP Binning And ROI GUI
Binning and Region Of Interest (ROI)
This window allows to select any single Region of Interest (ROI) on the chip and/or change the x and/or y binning factor.
As in the Main GUI, it has light blue on the status area, and dark blue on the control area
Original Geometry
The upper part shows the geometry of the array, where
Pres: prescan pixels
Data: Data area of the CCD
Overs: overscan pixels
amps: total amplifier on the X or Y direction
Total size: shows the total size that the image would have if using full size, calculated as
(Pres + Data + Overs) * amps, in the X direction
(Data) * amps in Y direction (no prescan or overscan area is used on Y)
Readmode: The upper left yellow is actually a control. It shows the currently selected read mode, and by clicking on it the mode can be changed.
The BLUE side supports left (shown on the image), right, or lowerboth (right and left) amplifiers
The RED side only supports left amplifier
Current Status
Shows the current status of the geometry, and allows (bottom part) to change it.
Note that Prescan and Overscan size cannot be changed from the GUI, and that's why on the bottom area the "Total size" stated for both columns (X) and rows (Y) corresponds only to the Data area
Read Time: Shows the total read time for the currently selected geometry. The calculation includes ROI, binning and readmode
show: If selected it will show, on the correspondent Real Time Display the ROI selected, as a blue (BLUE side) or red (RED side) thick line. This is just a quick guidance to the area that has been chosen.
ROI:
START: COLS, ROWS: starting pixel in x and y coordinates. The lower left corner corresponds to pixel (1,1)
LENGHT: COLS, ROWS: total size on X and Y
The image area of the ROI will be then: [Xstart, Ystart: (Xstart+Xlen), (Ystart+Ylen)]
OK: go select the choosen area.
full: selects the whole CCD as ROI (full frame). THis is equivalent to enter manually the full frame values.
The system can be set to start with a pre-selected ROI. For handling this, there are two buttons:
set to default: Use the currently selected ROI as the defaut, starting value. If this is done, the next time the system starts it will start with this ROI as a pre-selected value, and the next time the get default button is used it will restore to these values
get default: if a change was made, this button will restore the pre-selected default value.
BIN Factor:
Changes the binning factor on X and Y
OK: go change the binning.
The BLUE side has arbitrary binning factors for every direction (X and Y)
The RED side has only some allowed combinations (X, Y): (1,1) , (1,2) , (1,3) , (2,1), (2,2), (2,3) , (3,1), (3,2)
