Detailed description of the data product

To compute the 3d cosmic shear coefficients the following inputs are needed, along with a set of parameters described below.

Input Catalog

This fits catalog (coming from OU-SHE) is expected to contain the following columns:

  1. ID: Galaxy Id

  2. RA: Right ascension (unit defined as a parameter)

  3. DEC: Declination (unit defined as a parameter)

  4. E1: first component of ellipticity (mode, median, mean for instance)

  5. E1_SAMP: TBD samples under pdf of e1

  6. E2: second component of ellipticity (mode, median, mean for instance)

  7. E2_SAMP: TBD samples under pdf of e2

  8. Z: redshift (mode, median, mean for instance, used for binning)

  9. Z_SAMP: samples under pdf of z

  10. WEIGHT: weight for the galaxy

Input Random Catalog

The random fits catalog, obtained from VMPZ-ID (see Output Product: Photometric Random Catalog) will contains the following necessary columns:

  1. ID: Galaxy Id

  2. RA: Right ascension (unit defined as a parameter)

  3. DEC: Declination (unit defined as a parameter)

  4. Z: redshift (mode, median, mean for instance, used for binning)

  5. WEIGHT: weight associated to the galaxy

Running Parameters

The following parameters should be specified:

  • Input catalogs: path to files as previously described

  • Random catalogs: path to files corresponding to input catalogs, as previously described

  • Z Binning: A list of redshift bins, with min and max values
