TESTB/CCD

The command does a series of tests on a catalogue of bias frames. Since this commands produce the bias offset that is needed in most of the other test commands (( e.g. TESTF/CCD and TESTD/CCD), it should be the first command to be executed. It produces the following:

• A combined bias frame.
• A map of hot pixels in bias frames (obtained from a median stack of the raw bias frames);
• An ASCII and a MIDAS table containing the hot pixels;
• Plots of row and column averages of the mean bias;
• The mean bias level and standard deviations after hot pixel correction median filtering.
