Revision 0.72, date Mon_Jul_10_14:37:28_2017_-0400.
Usage: wcs-pv2sip [options] <input-wcs> <output-wcs>
[-o <order>] SIP polynomial order to fit (default: 5)
[-e <extension>] FITS HDU number to read WCS from (default 0 = primary)
[-S]: do NOT do the wcs_shift thing
[-s]: treat input as Scamp .head file
[-t]: override the CTYPE* cards in the WCS header, and assume they are TAN.
[-v]: +verboseness
Set the IMAGEW, IMAGEH in the output file:
[-W <int>]
[-H <int>]
Set the pixel values used to compute the distortion polynomials with:
[-x <x-low>] (default: 1)
[-y <y-low>] (default: 1)
[-X <x-high>] (default: image width)
[-Y <y-high>] (default: image width)
[-a <step-size>] (default: closest to 100 yielding whole number of steps)
