CosmoMC and bias parameter
Posted: February 15 2005
Hello,
I have a question concerning the twodf.f90 module of CosmoMC and the bias parameter.
I want to extract the value of the bias that is used in the analytic marginalisation over the matter power spectrum amplitude for a particular cosmological model. Can this be obtained directly from the analytic marginalisation formulas? I noticed that the following lines of code are commented out:
! CMB%norm(3) = sqrt(sum(th*Ninvd)/(sum1* 0.92**2) - 4./45*(CMB%omc+CMB%omb)**1.2) - &
! (CMB%omc+CMB%omb)**0.6/3
! write (*,*) CMB%norm(3)
and it gives me roughly what I'm looking for, but I don't recognise the formula here.
Thanks for your help
