Correction of field rotator-induced flat-field systematics-a case study using archived VLT-FORS Data
ESO's two FOcal Reducer and low-dispersion Spectrographs (FORS) are the primary optical imaging instruments for the VLT. They are not direct-imaging instruments, as there are several optical elements in the light path. In particular, both instruments are attached to a field rotator. Obtaining t...
