GETFITS(1)

💖 GETFITS(1) 💖

okay bestie, welcome to the User Commands section of the manual — yes this whole page lives there, and yes it's about to be your new obsession 💅

---

✨ NAME ✨

getfits — AME

---

🌸 SYNOPSIS 🌸

getfits -sv [-i num] [-o name] [-d dir] file.fits xrange yrange...

---

🦋 DESCRIPTION 🦋

no cap, the whole job here is: extract FITS files from FITS image files ✨

and there's more than one way to run this thing, so here are all of them, exactly as they are:

or : getfits -sv [-i num] [-o name] [-d dir] file.fits [x y dx [dy] ...

or : getfits [-sv1][-i num][-o name] [-d path] @fitslist xrange yrange

or : getfits [-sv1][-i num][-o name] [-d path] @fitslist x y dx [dy]

and here's what all those little letters and numbers actually mean, bestie, don't skip this part 🫶

• xrange: the columns to extract, written in the format x1-x2
• yrange: the rows to extract, written in the format y1-y2
• x y: the center pixel of the region you want to extract
• column row or hh:mm:ss dd:mm:ss system — that second one is sky coordinates 🌈
• dx dy: width and height in pixels of the region to extract
• (height is the same as the width if you omit it — she's flexible like that 💅)

---

🎀 the flags, one by one, periodt

• -d dir — writes the FITS file(s) into this directory 📁
• -i num — logs rows as they get copied, at this interval 👀
• -k file — a file full of keyword names to delete from the output header ✂️
• -o name — output name, for when you've just got one file 💖
• -s — writes the output to standard output 📤
• -x dx dy — dimensions of the image section to be extracted 📐
• -v — verbose 🗣️

and that's the whole page, you ate it 🍓

sooo this icon was brought to you by getfits from the fine folks over at EB_SOURCE, dated February 2026 — mwah, bye bestie 💜🦋✨
