Hi,
I have a simple question for Antony about CAMB. What is the reason CAMB does not allow the user to input values for the hubble parameter other than in the range [20,100] ?

I know it is easy to deactivate it, in camb.f90 in the CAMB_ValidateParams function, but I would like to know the reason why such a restriction was used. Is it perhaps that CAMB is not accurate enough in that area of the parameter space?

Thanks in advance,
Savas Nesseris

It certainly hasn't been tested outside that range (which is, of course, rather a lot of HST sigmas, so usually quite adequate).
