Detailed Description of the Data Product¶

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. It contains the following elements:

Data/RedshiftHistogram/

Key	Type	Description
BinCount	int	Number of redshift bins
CosmologyID	str	Cosmology identifier
ComovingDensity	ListOfDouble	Comoving number density in units (h/Mpc)3
CountdNdz	ListOfDouble	Differential number count dN/dz in redshift bins
RedshiftBinEdges	ListOfDouble	Edges of redshift bins

Keywords Extension Header CATALOG¶

This fits table is expected to contain the following keywords in primary HDU, characterizing the parameters of the product:
