WCSREMAP(1)

💫 NAME 💫

okay so bestie, meet wcsremap — straight out of the User Commands manual, and it's literally just described as "AME". That's it. That's the whole name line. Iconic levels of mystery, no cap. 🫶

---

🌈 SYNOPSIS 🌈

the way that you call it — two whole flavors:

remap [-v][-f WCSfile][-a rot][[-b][-j] ra dec][-i bits][-l num]
file1.fit file2.fit ... filen.fit

or, when you're feeling ✨ file-list-y ✨:

remap [-v][-f WCSfile][-a rot][[-b][-j] ra dec][-i bits][-l num] @filelist

---

✨ DESCRIPTION ✨

so basically wcsremap remaps FITS or IRAF images into a single FITS image using WCS. That's the whole vibe. Feed it a stack of images, get one glowy output back, and the WCS is the main character making it all line up. 💅

🎀 the flags, one by one, no skips

• -a — output rotation angle, in degrees (default 0). yes, you can spin the whole thing. spin it. 🌸
• -b ra dec — output center in B1950 (FK4) RA and Dec
• -e long lat — output center in ecliptic longitude and latitude
• -f file — use the WCS from this file as the output WCS
• -g long lat — output center in galactic longitude and latitude
• -i num — how many bits per output pixel (default is whatever the input had, fr fr)
• -j ra dec — center in J2000 (FK5) RA and Dec
• -l num — log every num rows of the output image
• -m mode — c = closest pixel (and "more to come", so watch this space 👀)
• -n num — the integer pixel value to use for blank pixels
• -o name — name for the output image
• -p secpix — output plate scale in arcsec/pixel (default = input)
• -s — set BZERO and BSCALE in the output file from the input file
• -t — number of samples per linear output pixel
• -u — delete distortion keywords from the output file
• -v — verbose (she will talk to you 🗣️)
• -w type — output WCS type (input is the default)
• -x x y — output image reference X and Y coordinates (default is the center)
• -y nx ny — output image dimensions (default is the first input image)

reminder bestie: those defaults are real defaults, not suggestions. -p falls back to the input's plate scale, -y falls back to the first input image's dimensions, -x falls back to the center, -i falls back to the input, and -a falls back to 0. 🩷

that's the whole page — every flag, every default, every word, all of it, nobody left behind. periodt. 🦋

this little ray of sunshine ships as source/version wcsremap EB_SOURCE, and it was dated February 2026 — so if you're reading it, you're right on time. mwah, go remap something gorgeous. 💖✨
