Detailed description of the data product¶

Final merged catalog with photometric and morphological information. It shall contain object positions, total fluxes, colors and some object characterization parameters. This product is an output from the MER_CatalogAssembly PE.

This is the main output product from MER. This catalog is used by the PHZ, SIR, SHE and SPE PEs.

The main elements inside this product are:

FilterList: List of filters that were used produce the catalog (e.g., VIS, NIR_Y, NIR_J, NIR_H, DECAM_g, OMEGACAM_u).
TileIndex (optional): The MER tile index.
FieldIdList (optional): List of unique IDs identifying the Euclid Fields overlapping with the studied region.
DataStorage: Element that links to a FITS file containing the catalog dataset.
ProcessingSteps (optional): Information about the processing steps associated with the production of the final catalog.

Bellow is a brief description of the columns contained in the catalog FITS file, needed by the LE3_GALEXT_ED PF:

Column name	Description	Unit
OBJECT_ID	Euclid unique source identifier
RIGHT_ASCENSION	Source barycenter RA coordinate (SExtractor ALPHA_J2000) decimal degrees	deg
DECLINATION	Source barycenter DEC coordinate (SExtractor DELTA_J2000) decimal degrees	deg
GAL_EBV	Estimated galactic E(B-V) at the source centroid according to the reference Planck map	mag
GAL_EBV_ERR	Error on galactic E(B-V) according to the reference Planck map	mag
