Detailed description of the data product
========================================
.. DetailedDescStart

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:
