Process flatfield measurements


This recipe processes data from a FLATFIELD observation and computes a new flatfield solution for each subarray. A responsivity map is created from this solution, and compared with the responsivity map derived from the existing solution. The results are displayed numerically and graphically (with each subarray in a separate window) for user assessment.

In addition a 3-d cube of the responsivity history is created for each subarray (provided a sufficient number of solutions exist), allowing stable bolometers to be identified for heater tracking.

The flatfield solution is kept on disk and stored in the calibration system; all other files created are deleted.



The results for each subarray are displayed in a separate Kapview window. The results displayed are:
