* <sup>(1)</sup> : 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).
 
 
* <sup>(2)</sup> : this amount of lost bolometer samples lost is essentially due to tests made during the CPV phase and aren't part of the surveys.
