wcs-pv2sip - Convert TPV WCS headers to SIP distortion headers
wcs-pv2sip [options] input-wcs output-wcs
- -o order
- SIP polynomial order to fit (default: 5)
- -e ext
- 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
- -W int
- Set the IMAGEW in the output file
- -H int
- Set the IMAGEH in the output file
- -x num
- x-low (default: 1)
- -y num
- y-low (default: 1)
- -X num
- x-high (default: image width)
- -Y num
- y-high (default: image width)
- -a size
- Set the pixel values used to compute the distortion polynomials with
(default: closest to 100 yielding whole number of steps)
