Cosmomc Matter Power Spectrum
Posted: April 04 2008
Hi Antony!
I'm studying the matter power spectrum. I discovered that actually mpk.f90 marginalizes over the amplitude of the power spectrum. What do you suggest if I need to fit also the normalization? Can I simply turn "Q_marge = F"? I tried to do that, but apparently the power spectrum output is a nonsense.
The reason why cosmomc doesn't care about the amplitude depends on the bad quality of the data?
Can you help me?
Thank you very much
Davide
