litebird_sim Interface

Data pre-processing

Class Description
LBSimProcessTimeSamples Standard container for pre-processed pointing information and time-ordered data from litebird_sim observations.
LBSimSharedMemProcessTimeSamples MPI shared-memory optimized container for pre-processed pointing information and time-ordered data from litebird_sim observations.

Noise covariance (and their inverse) operators

Class Description
LBSim_InvNoiseCovLO_UnCorr Inverse noise covariance operator for uncorrelated/white detector noise.
LBSim_InvNoiseCovLO_Circulant Inverse noise covariance operator for stationary noise with the covariance modeled as a circulant matrix.
LBSim_InvNoiseCovLO_Toeplitz Inverse noise covariance operator for stationary noise with the covariance modeled as a Toeplitz matrix.

GLS map-making functions and tools

Class / Function Description
LBSimGLSParameters Configuration parameters class for the GLS map-making solver.
LBSim_compute_GLS_maps Computes the GLS temperature and polarization maps from litebird_sim observations.
