plot cmb power spectrum

Post by fadakar golnaz » November 01 2013

dear guys does some one know how to plot cmb power spectrum with camb. i run the program and get below table



camb>VisualStudioRelease/CAMB_devel.exe params.ini
Reion redshift = 10.698
Om_b h^2 = 0.022600
Om_c h^2 = 0.112000
Om_nu h^2 = 0.00000
Om_Lambda = 0.725306
Om_K = 0.000000
Om_m (1-Om_K-Om_L) = 0.274694
100 theta (CosmoMC) = 1.037944
Reign opt depth = 0.0900
Age of universe/GYr = 13.794
zstar = 1088.71
r_s(zstar)/Mpc = 146.39
100*theta = 1.038226
zdrag = 1059.70
r_s(zdrag)/Mpc = 149.02
k_D(zstar) Mpc = 0.1392
100*theta_D = 0.160034
z_EQ (if v_nu=1) = 3216.24
100*theta_EQ = 0.846430
tau_recomb/Mpc = 284.87 tau_now/Mpc = 14384.7

Hi,

See http://camb.info/readme.html#outputs

You can use the output files with your preferred plotting program to plot the Cls.

If you have matlab, you can use the included matlab file plotcls.m
