## Processing a single IMB-FITS file

In order to calibrate a single science scan, one has to use the command `CALIBRATE`:

    MRTCAL> index build  ! Build index of files in current directory
    MRTCAL> mfind        ! Selects all the entries in index
    MRTCAL> mlist        ! List the entries in the Current indeX
    MRTCAL> file out myclassfile single  ! The usual CLASS command
    MRTCAL> calibrate 1  ! Where "1" is the entry number of the calibration scan
    MRTCAL> calibrate 2  ! Where "2" is the entry number of the science scan

The 2 last lines can also be merged in a single call:

    MRTCAL> calibrate 2 /with 1

As a result, only the 2 named scans are calibrated. The entries in the index file are also updated to reflect that their calibration has been done.
