low multipoles in Cosmomc

Post by marc vonlanthen » August 11 2009

Dear all,

I would like to know how to modify cosmomc in order to use it ignoring the lowest multipoles, i.e. to have l_min = 30 or even 50.

Than you

Marc

Just change the l-range of whatever datasets you are using.

Thank you for answering me.
For datas set like Acbar, clearly, it is sufficient to change the l-range. But my problem is with WMAP 5yr datas, for which you have to change the likelihood code... So if you have any suggestions, thanks in advance.

Marc
