This page gives definition of some words commonly used in this Explanatory Supplement.
- HFI detector set (aka detset aka quad) : a detector set is a combinaison of two pairs of Polarization Sensitive Bolometers pairs at the proper orientations. The lists of detsets is given in here.
- HFI effective beam : the effective beam at the map level is the overall angular response to the sky in a map pixel, which results from the combined effect of the instrumental response, the scanning strategy and the data processing.
- HFI focal plane geometry
- HFI HPR
- HFI IMO/RIMO
- HFI mission
- HFI optical beam
- HFI PBR
- HFI polarization leakage
- HFI ring : at the HFI DPC level the ring is the time intervalle between two First Thurster Firings as defined in AHF description document. It thus starts with a satellite slew and thus an unstable pointing period and continue with a satellite dwell and thus stable pointing period.
- HFI sample
- HFI scanning beam : the scanning is defined as the beam measured from the response to a point source of the full optical and electronic system, after the filtering.
- HFI survey (aka Scan #) : sky surveys are defined in terms of the direction of the satellite's spin axis. Survey periods are given here.
