Lambda prior in cosmomc
Is there any way to fix the prior for the cosmological constant in cosmomc. I'm using the parametrization with H and z_re. I thought that fixing z_re might fix lambda but that doesn't seem to work. Any suggestions?

Use a different parameterization that uses Omega_Lambda as a base parameter and then fix it in the input file. (i.e. write your own version of params_CMB for new parameter set)
