This module applies galaxy bias on a per-bin basis to galaxy power spectra. It reads bias values for each redshift bin and applies them to the appropriate auto- and cross-power spectra. Note that it only affects the galaxy_cl spectra not any galaxy-matter spectra.

For each pair of bins (i,j), the power spectrum is multiplied by b_i * b_j where b_i and b_j are the bias values for bins i and j respectively.

Assumptions

Galaxy bias is specified per redshift bin

Bias values are independent for each bin

Setup Parameters

None
