transfer function

Post by bin hu » May 18 2015

Hi everyone,

Are there some simple way to output transfer function for different parameter choices with the same sampling of k?

Many thanks!

In CAMB, you can set transfer_k_per_logint (to something larger than zero) to fix the k spacing.

Thanks, Antony, Yes. Figure it out. also need to set get_scalar_cls = F, otherwise, the num_q_trans is given by npoints instead of the one set from params.ini

Cheers, Bin
