Planck Public Data Release 3 Maps

Planck All Sky Maps are in HEALPix format, with Nside 1024 or 2048, in Galactic coordinates, and nested ordering. The signal is given in units of Kcmb for 30-353 GHz, or MJy/sr (for a constant νFν energy distribution ) for 545 and 857 GHz.

Unpolarized maps contain 3 planes, labeled I_Stokes (intensity), Hits (hit count), and II_cov (variance of I_Stokes).

Polarized maps contain 10 planes, labeled I_Stokes (intensity), Q_Stokes and U_Stokes (linear polarization), Hits (hit count), II_cov, QQ_cov, and UU_cov (variance of each of the Stokes parameters), and IQ_cov, IU_cov, and QU_cov (covariances between the Stokes parameters).

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
