This program is designed to test the effect of various options given in make_mwa_tied_array_beam on the calibration solution. The command line options for mwa_plot_calibration are a subset of those in make_mwa_tied_array_beam:
usage: mwa_plot_calibration [OPTIONS]
OPTIONS (RTS)
-m, --metafits=FILE FILE is the metafits file for the target observation
-c, --cal-metafits=FILE FILE is the metafits file pertaining to the calibration solution
-C, --cal-location=PATH PATH is the directory (RTS) or the file (OFFRINGA) containing the calibration solution
-N, --ncoarse_chans=NUM NUM is the number of coarse channels to include
-R, --ref-ant=TILENAME Override the reference tile given in pq_phase_correction.txt for rotating the phases
of the PP and QQ elements of the calibration solution. To turn off phase rotation
altogether, set TILENAME=NONE.
-U, --PQ-phase=PH,OFFS Override the phase correction given in pq_phase_correction.txt. PH is given in rad/Hz
and OFFS given in rad, such that, the QQ element of the calibration Jones matrix
for frequency F (in Hz) is multiplied by
exp(PH*F + OFFS)
Setting PH = OFFS = 0 is equivalent to not performing any phase correction
-X, --cross-terms Retain the PQ and QP terms of the calibration solution [default: off]
CALIBRATION OPTIONS (OFFRINGA) -- NOT YET SUPPORTED
-O, --offringa The calibration solution is in the Offringa format instead of
the default RTS format. In this case, the argument to -C should
be the full path to the binary solution file.
OTHER OPTIONS
-h, --help Print this help and exit
-V, --version Print version number and exit
