okay so this is imfill, and fr fr its whole thing is filling in the bad pixels. that's it, that's the era. 🎀

🌸 SYNOPSIS 🌸

[-v][-a dx[,dy]][-g dx[,dy]][-m dx[,dy]] file.fits ...

like… you hand it one or more file.fits and some flags, and it does the thing. slay. ✨

🦋 DESCRIPTION 🦋

Fill bad pixels in FITS and IRAF image files. no cap, that's the job — it goes in, finds the busted pixels, and patches them up so your data can be its best self. 💅

here's every single flag, bestie, and i'm not skipping a one of them:

• -a dx dy — Mean filter, dx x dy pixels. average-coded behavior, very demure. 🌸
• -b num — the bad pixel value. the default is BLANK or -9999, so if you don't say anything it just assumes that. 👑
• -f file — a FITS file that's all zeroes except at the bad pixels. it's giving "map of the damage". 💀
• -g dx x dy — Gaussian filter, dx x dy pixels. soft blur energy. 🧚
• -h halfwidth — the Gaussian half-width at half-height. yes that's the whole description, i'm just the messenger. 🫶
• -l num — logging interval, in lines. tells it how often to check in like a good friend. 🌈
• -m dx dy — Median filter, dx x dy pixels. the median is literally the main character of filters, i don't make the rules. ⭐
• -o — Allow overwriting of the input image. without this, it writes a new one instead, so like… tread carefully bestie, that's your original file on the line. 😭
• -p num [num] — minimum [maximum] good pixel value. the bracket one is optional, the first one isn't. 💜
• -v — Verbose. it will tell you everything it's doing, which is honestly iconic behavior. ✨

not me reminding you that -o overwrites your input image. it does. that's the whole point of the flag. it is not a vibe, it is a commitment. 🙈
