GCAL Flat field: GCAL flats are taken mixed with the science observations. For science programs one GCAL flat is obtained for each hour of open shutter time, though a minimum of two are always obtained. For example, for an observation that consists of 6x 30min of exposure time, a total of 3 ...
WebFlat field calibration is the most important operation performed on CCD data. This operation calibrates the relative response of the detector at each pixel. In some cases this is as simple as taking a special type of observation called a flat field. However, in many cases this calibration observation must be corrected for iillumination ... http://www.stargazing.net/david/QSI/ccdperfflats.html#:~:text=The%20purpose%20of%20flat%20field%20calibration%20is%20to,calibration%20image%20is%20one%20way%20to%20reduce%20vignetting.
