Planck Public Data Release 2 Maps

CMB Maps

CMB maps have been produced by the COMMANDER, NILC, SEVEM, and SMICA pipelines. For each pipeline we provide full-mission CMB intensity and polarization maps with associated masks.

In addition, there are six sets of maps from three data splits: first/second half-ring, odd/even years and first/second half-mission. Half-difference maps can be used to obtain an approximate noise estimate for the full mission, but they should be used with caution. Each split has caveats in this regard: there are noise correlations between the half-ring maps, and missing pixels in the other splits.

The intensity maps are provided at N_side = 2048, at 5 arcmin resolution, and the polarization maps are provided at N_side = 1024 at 10 arcmin resolution. All maps are in units of K_cmb. The Stokes Q and U maps are high-pass filtered to contain only modes above l > 30, as used for analysis by the Planck Collaboration.

Unfiltered CMB polarization maps, with versions R2.00 and R2.01, can be obtained from here, but are deprecated. See documentation for details.

The Pink cells indicate maps with polarization data, while the Blue cells are the maps with no polarization data.

The Common Masks

The common masks are stored in separate files for Temperature and Polarization. For intensity, we provide the UT78 and UTA76 masks at N_side=2048. For polarization, we provide the UP78, UPA77, and UPB77 masks at N_side=1024. Both files contain also a map of the missing pixels for the half mission and year coverage periods. The masks and the missing pixels maps are stored as separate columns in BINTABLE extension 1 of each file, named MASK-INT and MASK-POL, respectively.
