Planck Public Data Release 1 (PR1) Mission Science Maps
Note: These maps are PR1 (2013 release) products. For PR2 (2015 release) products, see the PR2 maps page.
The Planck All Sky Maps are made available as HEALPix (Hierarchical Equal Area isoLatitude Pixelization) files, which are implemented in FITS binary table format. For more information and software tools for analysis and display of HEALPix maps, please see http://healpix.sourceforge.net/.
Full channel maps are built using all the valid detectors of a frequency channel and cover the full mission (or the nominal mission for the 1st release). For HFI, the 143-8 and 545-3 bolometers are rejected entirely as they are seriously affected by RTS noise.
Single survey maps are built using all valid detectors of a frequency channel, but cover separately the different sky surveys. The single sky surveys are defined in terms of the direction of the satellite's spin axis: the first survey covers from the beginning of the science observations (the First Light Survey) to the time when the spin axis has rotated by 180 degrees (to the nearest pointing period), the following one covers from 180 to 360, and so on. Survey 1 dates span 20090813 to 20100213 while Survey 2 dates span 20100214 to 20100813 inclusive. The nominal mission spans 20090813 to 20101127 and is thus longer than the sum of survey 1 and 2.
Half-ring maps are built using only the first or the second half of the stable pointing period data. There are thus two half-ring maps per frequency channel named ringhalf_1 and ringhalf_2 respectively. These maps are built for characterization purposes in order to perform null tests.
