HFI(Planck) High Frequency Instrument Spectral Response

This section outlines the unit-conversion and colour-correction protocol for Planck/HFI(Planck) High Frequency Instrument, based on the measurements of the HFI(Planck) High Frequency Instrument detector chain spectral response (see Planck-2013-IX[1] and here for the description of the spectral response pre-launch measurements).

The band-averaged HFI(Planck) High Frequency Instrument spectral response data are shown in the figure below, and provided in the the instrument model. Similar data are available for individual detectors as well as sub-band averaged data sets (i.e., detset1, detset2, PSBs, SWBs). A table summarizing some of the spectral properties of the individual detectors, and band-averaged spectra, is shown at the bottom of this page.

The band-averaged spectrum for a given frequency band is derived using a hit-map-normalized inverse-square noise-weighted detector spectrum average. Thus, the effective band-averaged spectrum in question changes depending on Planck's coverage of the region of sky in question. This may change between different subsets of the Planck data, e.g., surveys, detector sets, etc. The histograms below demonstrate the variation across the sky of the detector weight coefficients used to determine the band-averaged spectra. Thus, the validity of using a single band-averaged spectrum for an entire sky map, may require evaluation depending on the task at hand. Some analyses may require incorporating the variation of the relative detector weights across the sky in order to understand the differential spectral transmission between complementary maps (e.g., detset-1 versus detset-2 maps). There are four groupings to consider with respect to the relative weighting of the individual detector contribution to the Planck data, and hence the relative contribution of a given detector spectrum to a band-averaged spectrum or sub-band-average spectrum: ring; detset; survey; and mask. There are three possible combinations for the ring grouping, accounting for whether the full ring is used in the map, just the first half, or the last half; the notation used here is F+L for the full ring, F for the first half, and L for the last half. The detset grouping has between three and five combinations per frequency band, accounting for the detectors to include in the average, including all detectors, detset1, detset2, only the PSB detectors (PSBs), or only the SWB detectors (SWBs). There are 11 possible survey options, including the full mission, nominal mission, Survey 1, Survey 2, Survey 3, Survey 4, Survey 5, Year 1, Year 2, Half-mission 1, and Half-mission 2. There are also six nominal masking options for the maps including 100%, 99%, 97%, 90%, 80%, and 60% of the sky (various degrees of masking the Galactic plane). Thus, for a given frequency band there could be up to almost 1000 (sub-)band-averaged spectra. While the images below only show the variation of detector contribution to the average for the full and nominal missions, a similar evaluation was conducted across the entire parameter space to determine the relevant average spectrum. This parameter space is also considered in determining the effective unit-conversion and colour-correction coefficients (see below).

Variation of individual detector contributions to band-averaged frequency maps across the sky, for various HFI(Planck) High Frequency Instrument surveys.


As described in Planck-2013-IX[1], several unit-conversion and colour-correction coefficients may be useful in the analysis of Planck data. These include conversion from CMBCosmic Microwave background temperature units to MJy sr-1, and colour-correction coefficients for conversion to a variety of spectral profiles. Software routines to determine these coefficients are provided here, and some example tables are provided here. A text file containing unit-conversion and colour-correction coefficients for all of the individual HFI(Planck) High Frequency Instrument detectors, as well as the band-averaged and sub-band-averaged spectra, is included at the bottom of this page. This file contains all of the iterations for the sub-band-averaged spectra, including ring, detset, survey, and mask variations.

The integration ranges used in determining the unit-conversion and colour-correction coefficients provided were verified through an iterative approach starting at one extreme and reducing to the band-centre for both the low and high frequency edges. The figure below demonstrates the stability in the integral once a sufficient data range has been employed. The range used in the official coefficients is thus sufficient to ensure that it falls within the flat region of the demonstration figure below.

The following table presents basic characteristics of the HFI(Planck) High Frequency Instrument detector spectral response, including optical efficiency, effective frequency, etc. Further details on the definition of these parameters are available in Planck-2013-IX[1].
