Make a catalog of sources randomly distributed on a line, square or cube.

TODO: is this useful enough for general use or should we hide it as an: internal method to generate test datasets?

Parameters:

size : int, optional

Number of sources

Number of dimensions

dmax : int, optional

Maximum distance in pc.

random_state : {int, ‘random-seed’, ‘global-rng’, RandomState}
