Schematic of the HFI pipeline. The left part of the schematic involves TOI and beams (this paper), while the upper-right part represents the map making steps (Paper B). Ancillary maps are composed of zodiacal light templates (ZL) and polarization band-pass mismatch (BPM) maps. ADC = analogue-to-digital converter (see Sect. 2). HPR = HealPix ring (see Paper B). “Beam products” refers to beam transfer functions, B_ℓ. Blue: changes in this release with section numbers corresponding to this paper. Yellow: released data products.
