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 | Full mission | From launch to the end of full mission |
|---|---|---|---|
| Duration | 473 days | 884 days | 974 days |
| Number of HFI packets generated onboard (HSK/science)(1) | |||
| Number of HFI packets lost on board (HSK/science) | 2 / 20 | 2 / 20 | 2 / 20 |
| Number of HFI packets lost on ground (HSK/science) | 0 / 0 | 0 / 0 | 0 / 0 |
| Number of retreived HFI packets (HSK/science) | |||
| Number of science samples stored in the database | 530 632 594 653 | 991 929 524 565 | 1 090 125 748 960 |
| Number of missing science samples | 17 050 | 65 310 | 7 521 758 (2) |
| Number of different housekeeping parameters stored in the database (HFI/SCS/sat) | align="center"|3174 / 708 / 12390 | ||
- (1) : science packets refer to the number of telemetry packets containing bolometer data when the instrument is in observation mode (Application Program Identifier = 1412). HSK packets refer to the number of HFI non essential housekeeping telemetry packets (Application Program Identifier = 1410).
- (2) : this amount of lost bolometer samples lost is essentially due to tests made during the CPV phase and aren't part of the surveys.
