Generation from In-Orbit Data

The basic idea is to obtain a supersky flatfield by combining a large number of relatively object-free exposures of random fields. A similar approach has been used to obtain WFPC superflats (Ratanunga et al. 1994, APJ, 108, 2362). Most suitable datasets are data from default configurations, because the entire detector area is covered. The detailed analysis steps are

The LargeScaleSens files can locally be validated using celestial objects in calibration offset pointings.
