Control mode for the CORALIE CCD
The controller parameters of the CCD CORALIE are:
| Description | Mode fast | Mode slow |
|---|---|---|
| Speed | 225 kHz | 67 kHz |
| Pixel reading time | 4.4 us | 14.9 us |
| Reading time | 19.6 s | 66.2 s |
| RON | 5.7 e- | 3.0 e- |
| Convertion Factor | 1.99 e-/ADU | 1.04 e-/ADU |
| Offset | 250 ADU | 230 ADU |
The gain in efficiency compared to the old CORALIE controller is considerable since for comparable (or even slightly better), the reading time increases from 74 to 20 seconds for the FAST and from 195 to 66 seconds for the SLOW.
