CircAn

CircAn(positions, r_in, r_out, *, validate=True)

Circular annulus in pixel coordinates.

Parameters

positions : tuple or array - like: Annulus center or centers as (x, y) pixel coordinates. Multiple centers are accepted as an (N, 2) array-like object. Coordinates are copied into owned, read-only float64 storage. Editing the input does not move the aperture; construct a new aperture to change centers. The positions attribute cannot be reassigned. C-order, Fortran-order, and strided inputs are accepted. Input (x, y) gives scalar sums; [(x, y)] gives length-one vector sums.
r_in : float: Inner and outer radii in pixels. r_in may be zero and must be smaller than r_out.
r_out : float: Inner and outer radii in pixels. r_in may be zero and must be smaller than r_out.
validate : bool = True: If False, skip input validation and assume finite geometry, ordered radii, and finite positions with shape (2,) or (N, 2). Coordinates are still copied and converted to float64.
