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.

IRAM Maps of the Crab nebula
Maps of the Crab nebula at 89.189 GHz (HCO+(1-0) transition) in both temperature and polarization, prodouced from observations performed at the IRAM 30m telescope from January 9th to January 12th 2009, are delivered as a tarball of 416 KB in the file
See README in the tarball for full details. These data were used in
