This module computes the eta parameter for the HMCode halo model based on the concentration amplitude parameter A. The relation eta = 0.98 - 0.12 * A is an empirical fit used in HMCode.
This parameter affects the transition between linear and nonlinear scales in the halo model calculation.
Assumptions
Empirical relation between eta and concentration amplitude A
