Detailed description of the data product

To compute the cosmic shear or galaxy-galaxy lensing 2-PCF, one (auto-correlation) or two (cross-correlation) input FITS catalogues with shear measurement are needed (see le3.wl.input.lensmccatalog in the following FITS descriptors).

FITS Input Catalog

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

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

  2. SHE_LENSMC_UPDATED_RA_CHAIN: O(200) samples under pdf of g1 [PD(200), 200float64 at max]

  3. SHE_LENSMC_UPDATED_DEC: Declination (unit in degree) [D, float64]

  4. SHE_LENSMC_UPDATED_DEC_CHAIN: O(200) samples under pdf of g2 [PD(200), 200float64 at max]

  5. SHE_LENSMC_G1: first component of ellipticity [E, float32]

  6. SHE_LENSMC_G1_CHAIN: O(200) samples under pdf of g1 (subset of what is produced by OU-SHE) [PE(200), 200float32 at max]

  7. SHE_LENSMC_G2: second component of ellipticity [E, float32]

  8. SHE_LENSMC_G2_CHAIN: O(200) samples under pdf of g2 (subset of what is produced by OU-SHE) [PE(200), 200float32 at max]

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

  10. SHE_LENSMC_WEIGHT: shear weight for the galaxy [E, float32]

Warning

We have discussed to add later in the main header

<IntegerKeyword name="SHE_SEL"/> <!-- ID of selection made (e.g. tomographic redshifts, stellar mass…) -->

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

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

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

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

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

Note that TOM_BIN_ID have replaced PHZ_MEDIAN.

Warning

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