comomc with wmap 9 year data
Posted: July 25 2014
Hi,
Could you please let me know which version of COSMOMC and CAMB was used to get the results which are there is WMAP 9 year papers.
I have found that using a different version of CAMB Likelihood can change as much as by 1.
Another thing is that WMAP 9 year used pivot scale 0.002 Mpc^{-1} however some of the versions of COSMOMC still has it 0.05 Mpc^{-1}.
One more issue is that CAMB uses log[10^{9}As] as parameter but COSMOMC parameter file supplies log[10^{10}As] how this thing is taken into account ?
