The message looks correct, if sampling thetastar you need to also sample omch2, ombh2 as H0 is not known a priori. If you are just using DESI data, there doesn't seem to be a strong reason not to just sample H0 and get thetastar as a derived parameter? (and if you want to impose a prior on thetastar cf https://github.com/CobayaSampler/cobaya/issues/18)
(@JesusTorrado perhaps we should add an example for priors on theory-derived to the doc somewhere, not sure it's explicitly covered?)
I'm trying to use the DESI BAO data along with the \theta_* (sound horizon at recombination) to obtain constraints on omega_m and H for w0waCDM model. I generated the relevant input file using cosmo generator. Here is the .yaml file
When I run the file, I get an error message
In cosmo generator I had set the parameter "Hubble parameter constraint" as "angular size of sound horizon at recombination". What can be a possible fix for the above problem
