hull_edge_mask¶

grizli.utils.hull_edge_mask(x, y, pad=100, pad_is_absolute=True, mask=None)[source]¶

Compute geometrical edge mask for points within a convex hull

Parameters

x, yarray: Coordinates of the catalog
padfloat: Buffer padding
pad_is_absolutebool: If True, then the buffer is taken from pad (e.g., pixels). If False, then pad is treated as a fraction of the linear dimension of the catalog (sqrt(hull area)).
maskbool array: Mask to apply to x/y before computing the convex hull

Returns
