🎀 edhead — bestie edition 🎀

okay so edhead is a little command from the WCSTools family, and it's here to help you edit the header of a FITS or IRAF image file 💖 that's the whole vibe. she's a General Commands Manual girlie, section 1, obviously. periodt.

✨ SYNOPSIS ✨

edhead [options] FITS or IRAF file(s)

---

💅 DESCRIPTION 💅

so basically, edhead opens up the header of the image file(s) you point at and lets you edit it using whatever editor you told the EDITOR environment variable to use 🦋 like, she respects your choices, she's not gonna force vim on you.

and here's the part that's lowkey iconic: edhead takes care of trailing spaces so you can literally just ignore them while you're in the editor 🌸 no stressing about invisible whitespace haunting your header, bestie. not today. not on her watch. 💅

---

🌈 OPTIONS 🌈

• -e <editor path> — set the editor yourself, right here, overriding whatever the EDITOR environment variable says. main character move tbh 👑
• -n — write a new file with .e before the file type extension 🎀 (default behaviour is to just overwrite the input file, which is giving brave ngl 🙈)
• -v — list the processing steps so you can watch her work 👀 very demure, very transparent

⭐ reminder bestie: by default edhead overwrites your input file, so if you're feeling cautious, that -n flag is your friend fr fr 🧚
