Detset Angular Power spectra[edit]

While the HFI is not providing sky maps obtained with different subsets of the detectors in a given frequency channel (see Detset maps), it provides auto-spectra and cross-spectra derived from these maps.


  • EFH to add the purpose of these spectra and of the associated covariance matrices, and a description of how they are obtained, including the inputs used to build them (maps, beams, mask),
  • AMo to add description of FITS file with sample header.
  • NB. contrary to the R1.00 (pre-)delivery, in the R1.10 final delivery each spectrum and associated covar matrix will be packaged together in a single file.
