is_in_window

pydl.pydlutils.mangle.is_in_window(polygons, points, ncaps=0)[source]

Check to see if points lie within a set of polygons.

Parameters:

polygons : PolygonList or FITS_polygon

A set of polygons.

points : ndarray or recarray

If points is a 3-vector, or set of 3-vectors, then assume the point is a Cartesian unit vector. If point is a 2-vector or set of 2-vectors, assume the point is RA, Dec.

ncaps : int, optional

If set, use only the first ncaps caps in polygon. This only exists to be passed to is_in_polygon().
Returns:

tuple()

A tuple containing two ndarray. First, a boolean vector giving the result for each point. Second, an integer vector giving the index of the polygon that contains the point.
