make_catalog_random_positions_cube#
- gammapy.astro.population.make_catalog_random_positions_cube(size=100, dimension=3, distance_max='1 pc', random_state='random-seed')[source]#
Make a catalog of sources randomly distributed on a line, square or cube.
This can be used to study basic source population distribution effects, e.g. what the distance distribution looks like, or for a given luminosity function what the resulting flux distributions are for different spatial configurations.
- Parameters:
- sizeint, optional
Number of sources. Default is 100.
- dimension{1, 2, 3}
Number of dimensions. Default is 3.
- distance_max
Quantity, optional Maximum distance. Default is “1 pc”.
- random_state{int, ‘random-seed’, ‘global-rng’,
RandomState} Defines random number generator initialisation. Default is ‘random-seed’. Passed to
get_random_state.
- Returns:
- table
Table Table with 3D position cartesian coordinates. Columns: x (pc), y (pc), z (pc).
