I have a basic question concerning priors (Gaussian or flat) on parameters in CosmoMC. If I add a new parameter, let's call it paramname:

1) if I want to give it a Gaussian prior via

Code: Select all

`prior[paramname]=mean std`

Code: Select all

`param[paramname] = center min max start_width propose_width`

Code: Select all

`prior[paramname]`

Code: Select all

`param[paramname]`

Thanks! Cheers,

Sunny
