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.
