Bases: object

assign_masses()

Assign spherical overdensity masses to halos. r must be sorted

Parameters:
  • h (struct haloflat) – Assign masses to this halo
  • r (np.ndarray) – Sorted array of particle radii
  • force_res (float) – Force resolution, below which density is smoothed.
  • dens_thresh (np.ndarray) – Thresholds for spherical overdensity mass calculation
  • early_termination (bool) – Specifies whether or not to terminate mass calculation when first particle density is below the lowest density threshold. If False, may lead to overestimate of SO masses for subhalos, but gives a better comparison to plain rockstar masses with STRICT_SO=1. Default: False
Returns:

Return type:

None
