# Pipeline for SO delensing study (L3.3)
This package contains Python codes for constructing B-mode lensing template from cosmic microwave background anisotropies (CMB) in curvedsky.
# Dependencies
The current code depends on the following python modules:
- numpy, healpy, pickle, matplotlib, configparser, sys
- mapsims (https://github.com/simonsobs/mapsims)
- cmblensplus (https://toshiyan.github.io/clpdoc/html/)
# Files
The main files for the analysis are as follows:
- simmap.py: generate simulated signal and noise maps for each frequency and patch
- cmb_map2alm.py: spherical harmonic transform of map to alm at each frequency and patch, and compute power spectra
- cmb_wiener.py: Optimally-combined alms from LAT and SAT with Wiener filtering.
- delens.py: construct lensing B-mode template and compute auto and cross spectra between lensing template and SAT B-modes
- gen_mass_sims.py: generate random Gaussian fields from the covariance of the mass-tracers.
- prjlib.py: read and define parameters and filename for analysis and some functions
- params.ini: parameter file
