HFIpreprocessingstatics

This page details the statiscs given in the pre-processing section.

The following table describes the different time intervals: Definition of the phases of the HFI mission:

The next table gives some statistics about the data handled at the pre-processing level:

-	Nominal mission	Scientific full mission	From launch to the end of full mission
Duration		884 days	974 days
Number of HFI packets generated onboard (HSK/science)
Number of HFI packets generated onboard (HSK/science)
Number of HFI packets lost on board (HSK/science)
Number of HFI packets lost on ground (HSK/science)
Number of retreived HFI packets (HSK/science)
Number of missing raw data packets/samples (HSK/science)
Number of data raw data samples stored in the database (HSK/science)
Number of different housekeeping parameters stored in the database (HFI/SCS/sat)
Number of pointing samples stored in the database

₍₁₎ : science packets is the number of telemetry packets containing bolometer data when the instrument is in observation mode.
