Product description[edit]

A general description of the product, including e.g. figures related to the contents (e.g. maps, tables), and some explanation of its scientific meaning. If there are scientific warnings about the use of the product (User’s caveats), they should also be given here, or at least references to other explanatory documents (papers etc).

Production process[edit]

Description of the Pipeline used to generate the product. In particular any limitations and approximations used in the data processing should be listed. Avoiding detailed descriptions of methods and referring to other parts of the ES and/or the relevant Planck papers for the details. References however should be quite detailed (i.e. it is not enough to direct the user to a paper, but the relevant section in the paper should be provided).


A list (and brief description to the extent possible) of the input data used to generate this product (down to file names), as well as any external ancillary data sets which were used.

Related products[edit]

A description of other products that are related and share some commonalities with the product being described here. E.g. if the description is of a generic product (e.g. frequency maps), all the products falling into that type should be listed and referenced.

Effective beams are located at nersc: and in both the HFI and LFI DPCs at:

    • On disk: /space/SimuData/effBeam_HFI_v41
    • DMC group: /data/dmc/MISS01/DATA/FEBeCoP_v41

Interface modules were developed to easily access the beams and the PSFs from the disk and the database. For HFI: The codes for reading the beams/PSFs and demonstration programs (http://cvs.planck.fr/cvs/Level2/Task_pkg/HL2_FEBeCoP/) FOr LFI:

The interface contains Fortran 90 routines to read the beams either from disk or from database. There are IDL routines also to read the beams from disk with detailed inbuilt help and fast examples.

There are two sets of (serial) demonstration programs:

  • to extract beams/PSF at any given set of pixels from disk/database and make .fits skymaps
    • beam_extract_f : extract beams from disk
    • beam_extract_f_PIO: extract beams from database
    • psf_extract_f  : extract PSF from disk
    • psf_extract_f_PIO : extract PSF from database
  • to make a full sky convolution of input maps with effective beams
    • effConv : convolve map reading beam from disk
    • effConv_PIO : convolve map reading beam from database

Example parameter files (with explanation) for these demonstration programs are available here: http://cvs.planck.fr/cvs/Level2/Task_pkg/HL2_FEBeCoP/params/

A detailed README on the usage of the routines and the programs are available as: http://cvs.planck.fr/cvs/Level2/Task_pkg/HL2_FEBeCoP/README.txt
