Description

This task converts the 'list' of given counts to magnitudes in the appropriate instrumental bandpasses. The 'list' can be a source-list from OMDETECT or a timeseries from EVSELECT or TRCON. The output file will be a FITS file identical to the input source-list or time-series except that the count-rates have been converted into instrumental magnitudes (in the specified filter bandpass - $U$, $B$, $V$, $UVW1$, $UVM2$, $UVW2$, clear) and the new magnitudes written as an extra column in the source-list FITS file. The program also calculates the limiting magnitude and writes the value in the source-list file. Presently the computed magnitude error is the maximum of the two asymmetric ones.
