Detailed description of the data product¶

This output product is the covariance and average of the angle-averaged 2PCF correlation at different separation scales. The product contains a FITS file with 2 HDUs named AVERAGE and COVARIANCE containing a list of keywords that specify the configuration used and a binary table with the average of the 2PCF realizations and the covariance.

XML Keywords¶

The product contains the following keywords:

Statistics: 2PCF type [ONE_DIM]
CountingMethod: Counting method [LINKED_LIST, KD_TREE]
BinTypeDim1: binning type along 1st dim
BinNumberDim1: Number of bins along 1st dim
BinMinValueDim1: Minimum separation scale Mpc/h along 1st dim
BinMaxValueDim1: Maximum separation scale Mpc/h along 1st dim
SplitFactor: Number of sub-catalogs in which the random catalog has been split for RR computation
UseWeight: Use object weight in the computation [true/false]
ReconstructionID: Identifirer for the reconstruction
CosmologyID: Identifier for the cosmology used
ReleaseName: Name of the release
FileNum: The number of realization used to compute the covariance
FileAdded: Name of the file added to the covariance computation [optional]
InputCross: Input products used are cross-correlation products
CovarianceFile: FITS file with the Average and covariance values
