wcs-pv2sip - Man Page

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)


Do NOT do the wcs_shift thing


Treat input as Scamp .head file


Override the CTYPE* cards in the WCS header, and assume they are TAN.



-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)
