Description
We describe the processing of the 336 billion raw data samples from the
High Frequency Instrument (HFI) which we performed to produce six
temperature maps from the first 295 days of Planck-HFI survey data.
These maps provide an accurate rendition of the sky emission at 100,
143, 217, 353, 545 and 857 GHz with an angular resolution ranging from
9.9 to 4.4'. The white noise level is around 1.5 μK degree or less in
the 3 main CMB channels (100-217 GHz). The photometric accuracy is
better than 2% at frequencies between 100 and 353 GHz and around 7% at
the two highest frequencies. The maps created by the HFI Data Processing
Centre reach our goals in terms of sensitivity, resolution, and
photometric accuracy. They are already sufficiently accurate and
well-characterised to allow scientific analyses which are presented in
an accompanying series of early papers. At this stage, HFI data appears
to be of high quality and we expect that with further refinements of the
data processing we should be able to achieve, or exceed, the science
goals of the Planck project.
