Bestfit Power Spectrum with action=2 in Cosmomc
Posted: August 29 2014
Hi everyone,
I'm trying to figure out where are the parameters that are used to generate the file "file_root.minimum.theory_cl" containing the bestfit data of the Power Spectrum.
Initially, I thought the bestfit parameters were those in "file_root.minimum", so I used them in CAMB expecting to obtain the same plot as with Cosmomc, but instead, I have found it doesn't match at all. The Cosmomc plot Is shifted upwards significantly compared to that generated by CAMB.
As an example, I am showing here the plot for the Grid PLA I have downloaded from: http://cosmologist.info/cosmomc/readme_planck.html, "base_planck_lowl_lowLike.bestfit_cl", and used those bestfit parameters in file "base_planck_lowl_lowLike.minimum" with CAMB (May 2014) and named this output "LCDM_scalCls.dat".

My question is, is it possible to generate with CAMB the same plot as that obtained from the file "file_root.minimum.theory_cl" generated by Cosmomc?
If so, where I can find those parameters?
