WFC - Library Flats and Biases

For each WFS run on the INT a series of library flat field and bias frames were created. The flat field frames were first bias-corrected using the master bias frames and the overscan region [1:50,1:4128] to monitor bias level; trimmed to the data region [51:2098,1:4100]; linearised see WFC foibles ; and finally imcombined within IRAF to create the library flats listed below.

These have been stored as 16 bit, gzipped binary files of roughly 10 Mbyte size and have (.gif) preview images, size of order 100 Kbyte, attached to the list.
