The analysis of calibration observations of targets and fields also observed from the ground has shown us that pixel to pixel sensitivity variations (flat field correction) if they exist are small, of the same order than the errors of the photometry (a few percent). Therefore PixToPixSens calibration file has been set to unity.

A similar conclusion was pointed out for LargeScaleSens (see 4.5.7)

We keep the following description as a guideline for eventual needs that might arise in the future.
