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: **Data/** +---------------------------+---------------------------+------------------------------------------------------------+ | Key | Type | Description | +===========================+===========================+============================================================+ | Area | float | Sky area covered by the catalog in deg2 | +---------------------------+---------------------------+------------------------------------------------------------+ | Concatenated | str | Boolean flag to indicate if tile concatenation was done | +---------------------------+---------------------------+------------------------------------------------------------+ | SelectionID | str | Selection identifier | +---------------------------+---------------------------+------------------------------------------------------------+ | SelectionName | str | Selection name | +---------------------------+---------------------------+------------------------------------------------------------+ | CalblockIdList | CalblockIdList | | +---------------------------+---------------------------+------------------------------------------------------------+ | Catalog | randomCatalogFile | Pointer to the FITS data file. | +---------------------------+---------------------------+------------------------------------------------------------+ | CatalogDescription | CatalogDescription | | +---------------------------+---------------------------+------------------------------------------------------------+ | IslandLabelList | IslandLabelList | | +---------------------------+---------------------------+------------------------------------------------------------+ | ObservationIdList | ObservationIdList | | +---------------------------+---------------------------+------------------------------------------------------------+ | PatchIdList | PatchIdList | | +---------------------------+---------------------------+------------------------------------------------------------+ | RedshiftHistogram | RedshiftHistogram | Histogram of number density along line of sight | +---------------------------+---------------------------+------------------------------------------------------------+ | SpatialCoverage | SpatialCoverage | | +---------------------------+---------------------------+------------------------------------------------------------+ | SpectralCoverage | SpectralCoverage | | +---------------------------+---------------------------+------------------------------------------------------------+ | TileIndexList | TileIndexList | | +---------------------------+---------------------------+------------------------------------------------------------+ The `RedshiftHistogram` element contains the number density along the line of sight.
