Hi all

I have a set of modified Friedmann equations and I would like to modify camb code to implement those modification and then use cobaya to constrain the parameters. Where can I add the modification to Friedmann equations in camb code. It would be great if somebody can help me with this.

Modify the functions in equations.f90.

Of course, if you only modify the background equations you cannot get consistent results for perturbations, only simple background things like H(z).
