gammaProf.mass_concentration.child2018(m200c, fit='nfw')[source]¶

Computes the predicted halo concentration, given a M_200c halo mass, using the c-M relation of Child et.al. 2018.

Parameters:	m200c (float) – The halo’s mass $M_{200\text{c}}$ in units of $M_{\odot} h^{-1}$ fit (string) – The set of fit parameters to use (Table 1 in Child+2018); options are ‘all’, ‘relaxed’, ‘nfw_stack’, or ‘einasto_stack’
Returns:	the concentration parameter $c_{200\text{c}}$
Return type:	float
