Concentration-mass relation from Duffy et al.(2008) [1].

It has the same fomulae as Bullock01Power, but with parameter values refitted.

See documentation for Bias for information on input parameters. This model has four model parameters.

Parameters

  • a (float) – Default is (11.0,-0.13,1.0,2.26e12).

  • b (float) – Default is (11.0,-0.13,1.0,2.26e12).

  • c (float) – Default is (11.0,-0.13,1.0,2.26e12).

  • ms (float) – Default is (11.0,-0.13,1.0,2.26e12).
