MSETUP CALIBRATION

        [MRTCAL\]MSETUP CALIBRATION Keyword Switch

    [MRTCAL\]MSETUP CALIBRATION SCAN NEAREST|LINEAR

    Define how to select the calibration scan used calibrate  science  data.
    In  NEAREST mode, the scan nearest in time will be used. In LINEAR mode,
    the algorithm will linearly interpolate calibration  parameters  between
    the two nearest calibration scans. Default is NEAREST.

    [MRTCAL\]MSETUP CALIBRATION OFF NEAREST|LINEAR

    Define how to select the OFF data matching the current ON data. In NEAR-
    EST mode, the OFF data nearest in time will be used. In LINEAR mode, the
    algorithm will linearly interpolate between the two nearest OFF spectra.
    This tuning is only meaningfull for On-The-Fly data. Default is NEAREST.

    [MRTCAL\]MSETUP CALIBRATION TSYS LINEAR|NEAREST

    Define  how  the  applied  system  temperature will be interpolated as a
    function of frequency. In NEAREST mode, the algorithm will use the  sys-
    tem temperature computed at the nearest RF frequency. In LINEAR mode, it
    will linearly interpolate the system temperatures surrounding  the  cur-
    rent frequency. Default is LINEAR.

    [MRTCAL\]MSETUP CALIBRATION BANDWIDTH Value

    Setup  the  desired calibration bandwidth in MHz. The nearest value that
    allows the division of the good spectra channels  of  each  chunkset  in
    equal virtual chunk sizes will be used. Exceptions are:
      - if value is 0, use the native hardware chunk size (no subdivision),
      - if  value  is larger than the native hardware chunk size, the latter
        is used instead (same as 0),
      - if value is lower than the channel spacing, the latter is  used  in-
        stead (all channels calibrated individually, use with caution).
    Default is 20 MHz.

    [MRTCAL\]MSETUP CALIBRATION POLARIMETRY YES|NO

    Choose  if  Mrtcal should calibrate or not the cross-polarimetry chunks,
    i.e. the REAL and IMAG ones. The others (NONE and AXIS) are always cali-
    brated. Default is NO.

    [MRTCAL\]MSETUP CALIBRATION FEEDBACK PIXEL|SET|ELEMENT

    Tune the granurality of the calibration results (Tsys, Tcal, Trec, ...).
    The median value per pixel, per chunkset, or per chunk element  will  be
    printed  in the PIXEL, SET, or ELEMENT mode, respectively. One value per
    chunk element may result in very long lists  when  using  virtual  chunk
    sizes (see MSETUP CALIBRATION BANDWIDTH). Default is SET.
