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

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.
