Detailed Description of the Data Product

This product is a mock catalog simulating the SEL-ID product and containing only the quantities needed for all the Galaxy Clustering Processing Functions. The purpose of this catalog is to provide test datasets to be used to verify and validate the processing functions. In the EUCLID LE3 pipeline, this product is replaced by the SEL-ID product.

Note

The density column in the FITS table is used only for testing purposes and is not expected to be provided by SEL-ID

XML Keywords

The product contains the following keywords:

Instrument

Identifier of the PF using the mock catalog

CatalogID

Type of mock catalog

CoordType

Coordinates used in the mock catalog [CARTESIAN, EQUATORIAL, PSEUDO_EQUATORIAL]

AngleType

Angular scales used [DEGREES, RADIANS]

ReleaseName

Name of the release using the product

Catalog

FITS file with input catalog

Catalog FITS file

The FITS type le3.gc.cat.test contains one binary table HDU named CATALOG with the following structure:

HDU CATALOG: 5 columns table
	Name	Description	Unit	Format
Columns	OBJECT_ID	unique identifier of source	NA	FITS 1K
	COORD_1	COORDINATE 1	NA	FITS 1D
	COORD_2	COORDINATE 2	NA	FITS 1D

Note

The values within the COORD_1, COORD_2 and COORD_3 columns depends on the COORD keyword. The CARTESIAN configuration uses X, Y, Z Cartesian distances. The EQUATORIAL configuration uses RA and Dec angles and the radial distance. The PSEUDO_EQUATORIAL configuration uses RA and Dec angles and the Redshift (z) of the object.
