💫 WCS-TO-TAN — manual page, but make it make sense 💫

okay so we're cracking open the astrometry.net manual, section 1, and the main character today is wcs-to-tan. pull up a chair, bestie, this one's short but she's got lore. 🎀

✨ NAME ✨

wcs-to-tan — an undocumented program of astromatic.net.

yes. that is genuinely what the page says. undocumented. she's mysterious, she's enigmatic, she's giving "no thoughts, just vibes" energy and honestly? respect. 💅

✨ SYNOPSIS ✨

wcs-to-tan

that's the whole thing. no arguments, no flags, no bracket notation. she just runs. the way the synopsis is literally just the program name with nothing else is so real of her. 👑

✨ DESCRIPTION ✨

ngl the description section here is basically just a list of flags with little one-liners, and we are not skipping a single one of them. every single flag gets its moment. periodt.

  • -w file — the WCS input file. this is the one you're reading from, your source material, your origin story. 🌸
  • -o file — the WCS output file. where the glow-up lands. ✨
  • -e extension — the FITS HDU number to read the WCS from. default is 0, aka the primary. so if you don't say anything, she assumes 0. simple as. 🦋
  • -t — just use the TAN projection, even if a SIP extension exists. like, even if there's SIP sitting right there. she said no thanks, we're doing TAN. 💀
  • -L — force WCSlib. yes ma'am, WCSlib, that's the one. 🔥
  • -x x-lo -y y-lo -W x-hi -H y-hi — the original page lists these four together and gives them no description at all. that's it, that's the whole entry. we don't know, she's not telling, and we are not about to make stuff up. 🙈
  • -N grid-n — same situation, bestie. the page gives no description for this one either. mysterious queen behavior. 💜
  • -v — Verbose. she will talk. she will tell you everything she's doing. main character narration mode activated. 😭
lowkey important note: -x, -y, -W, -H and -N have no documented descriptions on this page. i'm not gonna invent one for them — that would be fake news and we don't do that here. 🫶

✨ AUTHOR ✨

the Astrometry.net team made this. principal investigators are David W. Hogg (NYU) and Dustin Lang (CMU). absolute legends, no cap. 🧚

and that's the whole page, fr fr. this was version 0.56, dated July 2015 — a classic, a vintage, a little time capsule of a manual page. mwah. 💖 🌸 ⭐
