CosmoMC: Adding rd as a prior

[Jose Lozano]

Hello,

I'm trying to add r_drag measurement as a prior in CosmoMC. I just followed the recipe of the priors baryon_density.ini [omegabh2] or theta.ini [theta], However, it doesn't work properly. In which part one should modify to introduce r_drag as a prior?

I hope you can help me solve this small issue.

Kind regards,

Jose Lozano
