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_spectra : path
Input text file from CAMB, spectra unlensed
 cmb_seed : int
Numpy random seed for synfast, set to None for a random seed
 apply_delens : bool
If true, simulate delensing with taylens
 delensing_ells : path
Space delimited file with ells in the first columns and suppression factor (1 for no suppression) in the second column
Methods Summary
run_taylens
(self)Returns CMB (T, Q, U) maps as a function of observing frequency, nu. Methods Documentation

run_taylens
(self)[source] [edit on github]¶ Returns CMB (T, Q, U) maps as a function of observing frequency, nu.
This code is extracted from the taylens code (reference).
Returns: function – CMB maps.
