CAMB/CosmoMC with modified Hubble parameter?

Post by Abdolali Banihashemi » August 27 2018

We are working on a modified gravity model and wanted to know how our model can be constrained by CMB C_l's.

For the first approximation, we just want to modify the background i.e. Hubble parameter (with 3 new parameters) so we think we do not need to go beyond CAMB.

Would you please help us how can we just modify the Hubble parameter in CAMB? and how we should modify CosmoMC to constrain our new parameters in addition to standard parameters in the LCDM model?
