Getting Started

Here is a basic example to do some aperture photometry using CircularAperture and CircularAnnulus. The aperture_photometry function performs the photometry using a given method. 

data = ones(100, 100)
err = ones(100, 100)

ap1 = CircularAperture(50, 50, 3)
# partial overlap
ap2 = CircularAperture(0.5, 0.5, 5)

results = aperture_photometry([ap1, ap2], data, err)
@assert results.aperture_sum[1] ≈ 9π
@assert results.aperture_sum[2] ≈ 25π / 4

results
