Hi all,
I am trying to understand how Cl_hat, Fiducial_Cl and covariance matrix are read from the .dataset parameter file in order to run CosmoMC with a CMB gaussian likelihood (either the fiducial gaussian and the HL, namely 'gaussian' and 'HL' in CMBlike.f90)
Does someone actually knows whether such inputs must be provided in the [lmin-lmax] multipole range, or can be given from l=2 up to some l>lmax and then CMBlikes takes care of selecting the correct rows?
Just to be clearer, I am running it in 30<l<600, only T; I have set loin and lmax accordingly in the parameter file, provided the covariance matrix as a text with (lmax-lmin+1)x(lmax-lmin+1) dimension, and given fiducial Cls in 30-600 multipole range.
Thanks to everyone who's going to help me to figure this out! :)

Re: CosmoMC gaussian and HL likelihoods
I think the unbinned version is rather untested, so may not work, but the likelihood should take care of cutting the points/covariance as required by the inputs.
