Detector: | 2048 x 2048 pix, e2v back-illuminated CCD 42-40 |
Pixel scale: | 0.08 arcsec/pix unbinned |
Field-of-view: | 2.7 x 2.7 arcmin |
Dark current: | 0.55 e-/s/pix at -20 C |
Electronics gain: | 1.26 e-/DN |
Read-noise: | 9.5 e- |
Saturation: | 65,536 counts, or 82,500 e- |
Linearity: | XXXX |
Binning: | Default binning is 2x2, unless requested otherwise. |
Pre-flash: | Pre-flash is required to minimize image persistence. Can be disabled for a rapid time-series. |
Overhead: | 14 sec binned 2x2 with pre-flash; 7 sec without pre-flash. |
Cooling: | Thermal electric cooler stabilizes at -20 C in 30 min. |
Filters: |
