sumpix — AME

(yeah that's genuinely all it says. AME. mysterious queen behavior, no cap 😭 we move on.)

🦋 SYNOPSIS 🦋

sumpix [-dmrsv][-n num] x_range  y_range file.fit ...

that's the whole vibe check up front. ranges, then your .fit files, as many as you want, she'll handle them 🌸

🎀 DESCRIPTION 🎀

Sum row, column, or region of a FITS or IRAF image 💖

that's the whole thing she does and honestly? she ate. you point her at an image, you hand her an x range and a y range, and she sums that row / column / region for you. pookie energy.

the flags 👑

• -c x y r — compute the total counts in a circle of radius r centered at (x, y) 🫶 it's giving geometry slay
• -d — compute and print the standard deviation
• -e — compute and print the median
• -h — print column headers for the output values 👑
• -i — print the row or column number if the other one is 0
• -l — compute and print the min and max values
• -m — compute and print the mean
• -n — number of decimal places in the output ⭐
• -p — print the file name at the start of the line
• -r — compute and print the variance (sum of squares)
• -s — compute and print the sum — and yes bestie, this one is the default 💖
• -t — separate output values with tabs and add column headers
• -v — verbose

and under verbose, this lil note:

• a range of 0 implies the full dimension; an absence of ranges uses the entire image 🌈

so like… if you're not sure what to pass in the range slots, just don't pass anything and she'll take the whole entire image. generous queen 🧚
