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.

+--------------------+-------+-----------------------------------------------------------------+ | WEIGHT_TOT | float | Total weights | +--------------------+-------+-----------------------------------------------------------------+ | TILE_INDEX | int | Tile | +--------------------+-------+-----------------------------------------------------------------+ The number density function is calculated by interpolating the redshift distribution of the random catalog (after the correct normalization). The function is applied to both random and data catalogs. In DENSITY_SYS the angle dependence is accounted for by multiplying the number density by the systematic weight. FKP weights are calculated via :math:`w_{FKP} = \frac{1}{1/P + N \times Pk0}`, where P is the purity value (default set to 1), N is the number density and Pk0 is reference Pk amplitude. As of relase version SEL-ID 3.9, the WEIGHT_TOT is only WEIGHT_FKP. .. $PrintCatalog fit/euc-le3-id.xml le3.id.catalog.selected .. DetailedDescEnd
