💖 GET-HEALPIX(1) 💖

okay bestie, welcome to get-healpix, part of the astrometry.net family of tools 🌌✨ this little icon takes your coordinates and tells you which healpix</hotpix> they land in. that's it, that's the whole job, and she does it flawlessly 💅

🌸 NAME 🌸

get-healpix — Convert RA,DEC to Which healpix 🦋

✨ SYNOPSIS ✨

get-healpix [options] ra dec
get-healpix [options] x y z

like. two whole moods. either you're giving her sky coords (ra dec) or you're giving her 3D cartesian vibes (x y z). both are valid, both are slay 🫶

👑 OPTIONS 👑

  • -r — RA/DEC values in radians. the default is decimal degrees or H:M:S, so if you're not using this flag, keep it degrees, bestie 💜
  • -H healpix — plot twist ✨ take a healpix number as input and print its center as output. reversed the flow, main character energy.
  • -N n — Nside. the default is 1. yes, literally 1. small but mighty 🎀
  • -n — Print neighbours. because nobody's doing this alone, we love a supportive community 🌈
  • -R range — print healpixes within radius range in degrees. a whole little friend group of healpixes, obsessed 😭
  • -p — Project position within healpix. get those precise coordinates, no cap 🔥
⚠️ okay IMPORTANT, listen up: if your values are negative, add -- in between -r (if you're using it) and ra or x. do NOT skip this. the shell will absolutely eat your minus sign otherwise and it's giving chaos 💀
