MEASURE_READNOISE

Measures and files the readnoise for UIST from a set of dark frames

Description:

This recipe measures the readnoise for a group of five short-exposure UIST DARK frames and files that measurement with the calibration system. It also determines the readnoise variance. The readnoise result is compared with the nominal value; you are notified whether or not the value is within acceptable limits. The recipe appends a tabulation of the readnoise and its variance in a log file, $ORAC_DATA_OUT/uist_array_tests.log, which it creates with headings if the log does not exist.
