Getting Started
Here is a basic example to do some aperture photometry using CircularAperture
. The photometry
function performs the photometry using a given method.
using Photometry
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[1] ≈ 9π
@assert results.aperture_sum[2] ≈ 25π / 4
results
Table with 4 columns and 2 rows:
