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
