Hello,
I'm running CosmoMC with the some recent cosmological measurements (CMB, BAO, PantheonPlus).
When I run CosmoMC with action 4 (testing likelihoods), the values of chi^2 are different for BAO and CMB likelihoods in comparison when I run CosmoMC with action=2 (finding best fit values). Why does this discrepancy appears? The main LCDM parameters are not fixed but vary with reasonable bounds, including cal,kgal, xi, etc.
I will appreciate if someone can give me a hint or the cause of this discrepancies of chi^2 values.
Kind regards,
Jose
