This is a package for performing astronomical photometry using modern and efficient algorithms.
Inspired by photutils, SEP, and AperturePhotometry.jl.
Here is a basic example to do some aperture photometry using
photometry function performs the photometry using a given method. Please see the documentation for more examples and reference material.
data = ones(100, 100) err = ones(100, 100) ap1 = CircularAperture(50, 50, 3) # partial overlap ap2 = CircularAperture(0.5, 0.5, 5) results = photometry([ap1, ap2], data, err) @assert results.aperture_sum ≈ 9π @assert results.aperture_sum ≈ 25π / 4 results # output Table with 4 columns and 2 rows: xcenter ycenter aperture_sum aperture_sum_err ┌───────────────────────────────────────────────── 1 │ 50.0 50.0 28.2743 5.31736 2 │ 0.5 0.5 19.635 4.43113
Please see the to-do list above for project ideas as well as any open issues! If you add new functionality, please add appropriate documentation and testing. In addition, please increment the minor version of the package to reflect the new changes!
