Calibration Access and Data Handbook

Procedure

The extension LEDTEMPLATE of the OM CCF component PixToPixSens contains the normalized inverse illumination amplitude of each detector position. The array has a size of 2048x2048 elements. Bright areas in the internal flatfield data have assigned a value less than 1.0 and faint areas have a value of larger than 1.0. The SAS task applies the correction by multiplication of the returned array.

The function accesses the CCF LEDTEMPLATE map and returns an image with the requested size and resolution at the requested detector position. This functionality is identical to the functionality of CAL_omPixelSenseVariation (cf. section 3.5.15)
