Warping input/output files:
--xm XM A .fits binary or VO table. The crossmatch between the
reference and source catalogue.
--infits INFITS The fits image(s) to be corrected; enclose in quotes
for globbing.
--suffix SUFFIX The suffix to append to rename the output (corrected)
fits image(s); e.g., specifying "warp" will result in
an image like image_warp.fits (no default; if not
supplied, no correction will be performed).
catalog column names:
--ra1 RA1 The column name for ra (degrees) for source catalogue.
--dec1 DEC1 The column name for dec (degrees) for source
catalogue.
--ra2 RA2 The column name for ra (degrees) for reference
catalogue.
--dec2 DEC2 The column name for dec (degrees) for reference
catalogue.
Other:
--plot Plot the offsets and models (default = False)
--smooth SMOOTH Smoothness parameter to give to the radial basis
function (default = 300 pix)
--signal SIGCOL Column from which to get the signal for a signal-to-
noise cut (e.g. peak_flux) (no default; if not
supplied, cut will not be performed
--noise NOISECOL Column from which to get the noise for a signal-to-
noise cut (e.g. local_rms) (no default; if not
supplied, cut will not be performed
--SNR SNR Signal-to-noise ratio for a signal-to-noise cut
(default = 10)
Crossmatching input/output files:
--incat INCAT Input catalogue to be warped.
--refcat REFCAT Input catalogue to be warped.
--xmcat XM Output cross match catalogue
--corrected CORRECTED
Output corrected version of input catalogue
