💖 NAME 💖

wcs-pv2sip — bestie, this little cutie converts TPV WCS headers into SIP distortion headers. That's the whole job. She's a specialist. 👑

✨ SYNOPSIS ✨

wcs-pv2sip [options] input-wcs output-wcs

🌸 OPTIONS 🌸

  • -o order — the SIP polynomial order you want her to fit. Default is 5, no cap. 💅
  • -e ext — which FITS HDU number to read the WCS from. Default is 0, aka the primary. 🎀
  • -S — ok so this one says: do NOT do the wcs_shift thing. Just... no shifting. None. 🙈
  • -s — treat the input as a Scamp .head file. That's the vibe. 🦋
  • -t — override the CTYPE* cards in the WCS header and just assume they're TAN. Living dangerously, honestly. 😭
  • -v — plus-verboseness. The more you add, the more she yaps. ✨
  • -W int — set the IMAGEW in the output file. 🖼️
  • -H int — set the IMAGEH in the output file. 🖼️
  • -x num — x-low. Default is 1. ⭐
  • -y num — y-low. Default is 1. ⭐
  • -X num — x-high. Default is image width. 🌈
  • -Y num — y-high. Default is image width. 🌈
  • -a size — set the pixel values used to compute the distortion polynomials with. Default is whatever's closest to 100 that yields a whole number of steps. Math girlies rise 🫶
