CosmoMC: Adding new parameters

Post by Akhilesh Nautiyal(akhi) » March 03 2008

Hi,
I want to modify the power spectrum in CAMB. The modified power spectrum contains some new parameters. I want to find their best fit values using CosmoMC.

I would be glad to know what changes I should do in CosmoMC and CAMB to include new parameters.

Looking forward for your kind help.

Hi,

Change the number of parameters in /source/settings.f90
add the new parameter in /camb/indriver.F90 , /camb/power_tilt.f90 and params.ini

Also make the changes in params_CMB.covmat.

Try this.

best wishes!
Minu Joy
