Detailed description of the data product

To compute the 2 point statistics position-position (aka angular) or shear-position (aka galaxy-galaxy lensing), an input FITS catalogs with position of lenses is needed (see le3.wl.2pcf.input.poscatalog in the following FITS descriptors). This catalog can be the same as for the sources, or optionally (as described here) a separate catalogues with a different selection.

FITS Input Catalog

This fits catalog (coming from OU-SHE/OU-PHZ) is expected to contain (in hdu named “POS_CATALOG”) the following columns:

  1. RIGHT_ASCENSION: Right ascension (unit in degree) [D, float64]

  2. DECLINATION: Declination (unit in degree) [D, float64]

  3. TOM_BIN_ID: selection bin (labelling from PHZ using SWG prescriptions, based in particular on tomographic redshift) [J, int32]

Warning

The following columns for selection have been discussed by SWG WL but no agreement yet with PHZ PF that is expected to produce them :

  1. Z_BIN: tomographic redshift bin (labelling from PHZ using SWG prescriptions)

  2. RF_COLOUR_BIN: Bin in Rest-frame colour (labelling from PHZ using SWG prescriptions)

  3. MASS_BIN: Bin in stellar mass (labelling from PHZ using SWG prescriptions)

  4. APP_MAG_BIN: Bin according to apparent magnitude (labelling from PHZ using SWG prescriptions)

  5. REDMAG_BIN: redmagic-like selection from PHZ (luminous red galaxies,labelling from PHZ using SWG prescriptions)

  6. FITCLASS: star/galaxy separation from SHE : galaxy (0), star(1), unknown (2)

  7. WEIGHT: weight associated to the galaxy [E, float32]

Note that TOM_BIN_ID have replaced PHZ_MEDIAN.

Warning

This input catalogue is a catalog container, containing in particular an associated spatial footprint propagated to outputs.

Warning

We have discussed to add later in the main header
