This page documents the 600 lensing maps (healpy alm fits file, lmax=3000) available at


There are 6 type of maps, labeled with

sim_ptt_????_lmax3000.fits : lensing map from temperature only, simulation index ???? 0000 to 0099

sim_p_p_????_lmax3000.fits : lensing map from polarization only

sim_p_????_lmax3000.fits : lensing map from temperature and polarization (MV)

sim_xtt_????_lmax3000.fits : lensing curl map from temperature, useful for null tests

sim_x_p_????_lmax3000.fits : lensing curl map from polarization

sim_x_????_lmax3000.fits : lensing curl from temperature and polarization (MV)

For illustration, the temperature (TT), polarization (PP) and Minimum Variance (MV) Wiener-filtered displacement reconstructions, together with the input, for realization 99:

The cross-correlation correlation to the input maps, as calculated across the entire patch is roughly like this:


The mean-field (here, contribution from the mask and noise anisotropies) has not been subtracted out from the maps on disk. The mean-field spectra look like this:

The mean-field subtraction can be performed subtracting the lensing reconstructed maps averaged over a subset of the simulations.
