| Abstract: | The Planck High Frequency Instrument (HFI) has observed the full sky at six
frequencies (100, 143, 217, 353, 545, and 857 GHz) in intensity and at four
frequencies in linear polarization (100, 143, 217, and 353 GHz). In order to
obtain sky maps, the time-ordered information (TOI) containing the detector and
pointing samples must be processed and the angular response must be assessed.
The full mission TOI is included in the Planck 2015 release. This paper
describes the HFI TOI and beam processing for the 2015 release. HFI calibration
and map-making are described in a companion paper. The main pipeline has been
modified since the last release (2013 nominal mission in intensity only), by
including a correction for the non-linearity of the warm readout and by
improving the model of the bolometer time response. The beam processing is an
essential tool that derives the angular response used in all the Planck science
papers and we report an improvement in the effective beam window function
uncertainty of more than a factor 10 relative to the 2013 release. Noise
correlations introduced by pipeline filtering function are assessed using
dedicated simulations. Angular cross-power spectra using datasets which are
decorrelated in time are immune to the main systematic effects. |
