LIkelihodd for l upto 200

Post by Akhilesh Nautiyal(akhi) » May 26 2008

Hi all,


I am trying to run WMAP 5yr likelihood code l upto 200. I changed integer :: ttmax = 200 in place of integer :: ttmax = 1000 in WMAP_5yr_options.F90 file and we also changed the test_cls_v3.dat such that it contains data upto l=200 . I am getting
following output.


WMAP likelihood evaluation report:
no errors
------------------------------------------------------------
------------------------------------------------------------------
Breakdown of -2ln(L)
------------------------------------------------------------------
MASTER TTTT = 187.051160 for 168 ls
Beam/ptsrc TT correction = 0.410116
low-l TTTT gibbs = -10.645216
MASTER TETE chi2 = 174.473069 for 177 ls
MASTER TETE det = -2363.594712
TT/TE/EE/BB low-l chi2 = 1232.786033 for 1170 pixels
TT/TE/EE/BB low-l det = 0.000000
------------------------------------------------------------------
TOTAL -2ln(L) = -779.519549
------------------------------------------------------------------
Expected -2ln(L) = 2658.871392
Difference = -3438.390941
------------------------------------------------------------------
Please let me know how to get positive -2ln(L) or whether the result is OK.

Hi Akhilesh,

You posted this message more than one year ago, and I hope you fixed the problem. If it is the case, you can maybe help me, because I would like to begin the simulation at l_min=60. It is the opposite of what you did, but the procedure should be similar.

Thanks,

Best regards,

Marc
