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

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.
