Detailed Description of the Data Product

This catalog contains all the sources from the SIM True Universe Galaxy Catalog Products that overlap the inner core area of a given MER tile. This product is intended to be used as an input product for the MER analysis pipeline.

The main elements inside this product are:

  • SpatialCoverage: The catalog spatial coverage.

  • SpectralCoverage: The catalog spectral coverage with a list of the filters that were used to produce the catalog (e.g., VIS, NIR_Y, NIR_J, NIR_H, DECAM_g, LSST_g).

  • TileIndex: The MER tile index.

  • PatchIdList (optional): The sky patch ids associated to the product.

  • ObservationIdList (optional): List of unique IDs identifying the Euclid observations that were used to generate the product.

  • CalblockIdList (optional): The calibration block ids associated to the product.

  • Release: The SIM True Universe galaxy catalog release version.

  • DataStorage: Element that links to a FITS file containing the catalog data set.

These are the columns contained in the main catalog FITS file:

Column name

Description

Unit

SOURCE_ID

Unique id

NA

HALO_ID

Unique halo id coming from the Flagship dark matter halo catalog

NA

KIND

Galaxy type: 0: CENTRAL, 1: SATELLITE, 2: QSO, 3: HIGH REDSHIFT, 4: STRONG-LENSING, 5: GLOBULAR-CLUSTER

NA

RA

right ascension equatorial coordinates

deg

DEC

declination in equatorial coordinates

deg

RA_MAG

magnified right ascension

deg

DEC_MAG

magnified declination

deg

Z_OBS

redshift with peculiar velocity

NA

REF_MAG_ABS

absolute magnitude used to scale emission lines width (usually in the r-band filter redshifted at z=0.1)

NA

REF_MAG

magnitude used to rescale template (usually apparent SDSS r band z=0.1 AB magnitude, but absolute for QSO and High-z. Does not include lensing magnification)

NA

BULGE_FRACTION

ratio of the flux in the bulge component to the total flux (often written B/T). For stamp creation

NA

BULGE_R50

half light radius of the bulge. For stamp creation

arcsec

DISK_R50

half light radius of the disk. For an exponential profile (or Sersec profile with index n=1), disk_r50 = disk_scalelength * 1.678. For stamp creation

arcsec

BULGE_NSERSIC

Sersic index of the bulge component. For stamp creation

NA

BULGE_AXIS_RATIO

Bulge projected axis ratio (b/a). For stamp creation

NA

INCLINATION_ANGLE

Galaxy inclination angle (where 0 degrees = face-on and 90 degrees = edge-on). Galaxy ellipticity for disk and bulge components are computed following the recipe in https://euclid.roe.ac.uk/projects/sgsshear/wiki/SHE-SIM. For stamp creation

deg

DISK_ANGLE

position of the disk rotation axis (degrees) (assumption: bulge_angle = disk_angle). TU Galaxy stamps convention for OU-SIM: the standard is to set the position angle from North to East, with the major axis aligned in Declination. For stamp creation

deg
