  Files needed:
  • Download the HFI-545 and HFI-857 maps from the HSC/SPIRE FTP area. These maps are derived from the ones available in the Planck Legacy Archive, but convolved with an 8 arcmin Gaussian beam in order to circularize the effective map beams, plus the maps absolute offset as estimated by the Planck-HFI team via cross-calibration with FIRAS (see Planck Collaboration VIII. 2013, In preparation)

  • If you are using HIPE 10.x, download the colour correction table file SpireHfiColourCorrTab_v1.1. This step is not needed if you are using HIPE 11 or later versions as the proper colour correction file is already included in the build.
  The offsets are computed on extdPxW maps, calibrated for extended emission, with extended gain correction applied and in units of MJy/sr (as explained in the section 5.7 of the SPIRE Data Reduction Guide). Hence, the re-processing will start from a level-1 context (which may be the result of merging multiple observations, see e.g. the Photometry Map Merging scirpt available in HIPE under the menu ScriptsSPIRE Useful script) and then executing the zeroPointCorrection task with one of the following methods:

  1. Run the zeroPointCorr.py script. It assumes that a Level1Context and Level2Context are already defined and named level1 and level2, respectively. It also sets three required properties needed by the zeroPointCorrection task, i.e. the location of two HFI maps and the colour correction table: please modify the PATH_TO_FILE accordingly to your set-up.

  1. If you are using HIPE 10, run the zeroPointCorr_HIPE10.py script. It assumes that the observation has been reduced with HIPE 10 or previous versions. It also sets three required properties needed by the zeroPointCorrection task, i.e. the location of two HFI maps and the colour correction table: please modify the PATH_TO_FILE accordingly to your set-up.
  2. If you are using HIPE 11, run the zeroPointCorr_HIPE11.py script. It assumes that the observation has been reduced with HIPE 11 or later versions. It also sets the location of the two Planck maps by the zeroPointCorrection task: please modify the PATH_TO_FILE accordingly to your set-up.
 
  1. Alternatively, run the correction using the SPIA interface (SPIRE Photometer Interactive Analysis). In order to be able to run the zeroPointCorrection task, the user.props file present (by default) in you $HOME/.hcss directory must be modified and the following lines added (please modify the PATH_TO_FILE accordingly to your set-up):
    • spire.spg.hfi.545map = PATH_TO_FILE/DX9_map_545_smooth_8arcmin.fits
    • spire.spg.hfi.857map = PATH_TO_FILE/DX9_map_857_smooth_8arcmin.fits

    • spire.spg.hfi.colorc = PATH_TO_FILE/SpireHfiColourCorrTab_v1.1.fits
