cosmomc:Using H0 as an input rather then \\theta, couldn''t

Post by Akhilesh Nautiyal(akhi) » February 10 2012

HI,

I would like to use [tex]H0[/tex] as an input parameter in params.ini rather then \theta as I want to fix it to the mean value from WMAP7 and doesn't want it to vary.
bit since I have to use \theta as an input parameter, I couldn't find how to do it.One way was to use params_H rather then params_CMB but I couldn't locate it anywhere in the cosmomc website.

I will be grateful if I can get it or get help to change the code accordingly.


Regards,
Akhilesh

I think I removed the link because the module was so old that updating it to work with the latest cosmomc would take more work than modifying the default parameterization file (params_CMB.f90).

Dear Antony,

I tried to modify params_CMB.f90 file but I couldn't get the expected results. I will be grateful if you can kindly let me know where to modify in this file.

Regards,
Akhilesh
