Science target templates

The companion python package ScopeSim-Templates contains a library of helper functions for generating ScopeSim-friendly Source objects for various common astronomical sources.

For more information, please see the ScopeSim-Templates documentation

A basic star cluster

my_cluster = sim_tp.stellar.clusters.cluster(mass=1000.0,       # [Msun]
                                             distance=8000,     # [pc]
                                             core_radius=1)     # [pc]
my_cluster.plot()

A basic elliptical galaxy

my_elliptical = sim_tp.extragalactic.galaxies.elliptical(half_light_radius=30,   # [arcsec]
                                                         pixel_scale=0.1,        # [arcsec]
