BBN in cosmomc
I am looking to play around with the BBN values in cosmomc. They seem to be hard coded. Can anyone please point in the direction of their location? Thanks!
Cheers

calclike.f90: if (Use_BBN) GetLogLikePost = GetLogLikePost + (CMB%ombh2 - 0.022)**2/(2*0.002**2)

I obtained the same instance when I greped 'BBN' in the source. I was curious if there were any other instances of it in the code from which I could alter its values? Thank you

Hi There,
I am new to CosmoMC, but it looks great!
I have been asked to reproduce WMAP5 + BAO results (Percival et al 2007).
My only problem is that i am not sure in which form i have to include the likelihood.
Let me explain my problem: -2lnL = X^-1 V^-1 X
Now when i add this to calclike.f90 i have
if (use_percival)
GetLogLikePost = GetLogLikePost + X^-1 V^-1 X
end if
Is it correct? Or i have to use X^-1 V^-1 X /2
Looking forward to hearing from you :)
