The fors_remove_bias recipe

fors_remove_bias

Synopsis

Subtract bias from input frame

Description

This recipe is used to subtract the overscan and master bias(produced by the recipe fors_bias) from one raw data frame. The overscan regions, if present, are used to compensate for variations of the overall bias level between master bias and input raw frame. The overscan regions are then trimmed from the result.

The recipe should allow any fors frame.
