cluster_toolkit.boostfactors module

Galaxy cluster boost factors, also known as membership dilution models.

cluster_toolkit.boostfactors.boost_nfw_at_R(R, B0, R_scale)[source]

NFW boost factor model.

Parameters:
  • R (float or array like) – Distances on the sky in the same units as R_scale. Mpc/h comoving suggested for consistency with other modules.
  • B0 (float) – NFW profile amplitude.
  • R_scale (float) – NFW profile scale radius.
Returns:

NFW boost factor profile; B = (1-fcl)^-1.
Return type:

float or array like
cluster_toolkit.boostfactors.boost_powerlaw_at_R(R, B0, R_scale, alpha)[source]

Power law boost factor model.

Parameters:
  • R (float or array like) – Distances on the sky in the same units as R_scale. Mpc/h comoving suggested for consistency with other modules.
  • B0 (float) – Boost factor amplitude.
  • R_scale (float) – Power law scale radius.
  • alpha (float) – Power law exponent.
Returns:

Power law boost factor profile; B = (1-fcl)^-1.
Return type:

float or array like
