CMBLensed
(nside, cmb_spectra, cmb_seed=None, apply_delens=False, delensing_ells=None, map_dist=None)[source] [edit on github]¶ Bases:
pysm.CMBMap
Lensed CMB
Takes an input unlensed CMB and lensing spectrum from CAMB and uses Taylens to apply lensing, it optionally simulates delensing by suppressing the lensing power at specific scales with the user provided
delensing_ells
. Parameters
 cmb_spectrapath
Input text file from CAMB, spectra unlensed
 cmb_seedint
Numpy random seed for synfast, set to None for a random seed
 apply_delensbool
If true, simulate delensing with taylens
 delensing_ellspath
Space delimited file with ells in the first columns and suppression factor (1 for no suppression) in the second column
