Read out times: e2v CCD#14 and CCD#15
The table below contain readout times of the CCDs.
CCD#14 is in ALFOSC and the default readout speed is 200.
FIES contains CCD#15 with the default readout speed of 100.
The four readout speeds are: 100, 200, 400, and 800 Kpixels/sec.
The readout speeds useful for science are : 100, 200, and 400 Kpixels/sec.
Window | 100 kpxl/s | 200 kpxl/s | 400 kpxl/s | 800 kpxl/s |
| bin 1x1 | bin 2x2 | bin 1x1 | bin 2x2 | bin 1x1 | bin 2x2 | bin 1x1 | bin 2x2 |
full frame 2198x2102 | 45 s | 15 s | 25 s | 10 s | 15 s | 7 s | 9 s | 5 s |
Note : the full frame window includes overscan pixels
Note : For every command you issue (exp, mexp) add an additional overhead of 2 seconds.
Example : Total time spent for a full frame, bin 1x1, mexp 10 5 command at 200 Kpix/sec readout speed:
2 sec overhead for mexp command + (10 sec integration + 25 sec readout time) x 5 exposures = 177 sec
