Specially processed maps

Overview

This section describes products that require special processing. Only one such product is available at this time; this section will be expanded with time as more products are added.

Lensing map

We distribute the minimum-variance (MV) lensing potential estimate presented in as part of the 2014 data release. This map represents an estimate of the CMB lensing potential on approximately 70% of the sky, and also forms the basis for the Planck 2014 lensing likelihood. It is produced using filtered temperature and polarization data from the SMICA DX11 CMB map; its construction is discussed in detail in .

The estimate is contained in a single gzipped tarball named COM_CompMap_Lensing_2048_R0.00.tgz. Its contents are described below.
