Empirical bias from Tinker et al (2005).

See documentation for Bias for information on input parameters. This model has no free parameters.

Notes

This form is the same as that of SMT01, however the parameters were re-fit to simulations in [1]. Here the default parameters are (a,b,c) = (0.707, 0.35, 0.8).
