Detailed Description of the Data Product
_________________________________________
.. DetailedDescStart

This data product contains the selected Data or Random catalog for the spectroscopic galaxy clustering analyses.
It contains a minimal set of columns needed for the clustering analyses, namely the spatial coordinates and a weight.

Note that the Data and Random catalogs share the same data product definition.

This catalog is stored in a FITS file. The second HDU is a binary table extension that contains
metadata in the keywords and the catalog in the data table.

Metadata
++++++++
The metadata stored in the Data element of the XML contains useful information about the survey coverage. Here is a brief summary of the metadata:
