WCS-XY2RD(1)

✨ WCS-XY2RD ✨

okay bestie, welcome to wcs-xy2rd, part of the astrometry.net manual (section 1, the cool section πŸ’…). This is the little tool that takes your pixel coordinates (x,y) and turns them into sky coordinates (RA,Dec). it's giving ✨coordinate glow-up✨. no cap.


🌸 SYNOPSIS 🌸

wcs-xy2rd [options] -w file

that's it, that's the vibe. you hand it a WCS file, you hand it points, it hands you the sky. πŸ¦‹


πŸŽ€ OPTIONS πŸŽ€

  • -w file β€” the WCS input file. literally the whole reason we're here, bestie. this one's required.
  • -e extension β€” which FITS HDU number to read the WCS from. default is 0, aka the primary. 🏠
  • -x pixel -y pixel β€” specify a single point to convert, and the result gets printed to stdout. one point, one moment, main character energy. ⭐
  • -t β€” just use the TAN projection, even if a SIP extension exists. like, we're keeping it simple today.
  • -L β€” force WCSlib. WCSlib girlies rise.
  • -T β€” force WCStools. WCStools stans, this one's for you.
  • -s β€” print sexigesimal too. yes queen, give us the full RA/Dec serve. πŸ‘‘
  • -i file β€” the xyls input file.
  • -o file β€” the rdls output file.
  • -f index β€” xyls field index. default: all of them. no picking favourites unless you say so.
  • -X name β€” the X-column-name.
  • -Y name β€” the Y-column-name. (yep, capital X and capital Y, they're a matched set 🫢)
  • -v β€” +verbose. the plus is doing numbers here, that's just how it's written.
