Hi,I'm trying to figure out how to perform a fit to some BAO measurements alone (so, measurements of DM/rdrag, DH/rdrag and similar). How do I set up the parameters correctly for this in Cobaya...

You can use derived parameters to sample Omega_m etc in the same way that As and logA are handled in the presents you can see in "cobaya-cosmo-generator" GUI. However, since rdrag is theory model...
