Dark frames are taken rarely. Used CCD modes are: high gain, 4 and 1 ports. The typical exposure time is 1800 sec. The FORS pipeline generates master DARKs from input raw DARKs with master BIAS subtracted. Dark current: is computed in from the median master dark frame level in ADU/hr/px and transformed into electrons by using the conversion factor CONAD (in the case of 4 ports a mean CONAD is used).
General information
Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
