Detailed description of the data product¶

To compute the Galaxy Clustering Two-point Correlation Function, a parameter file specifying the configuration is needed. The configuration file contains all the information about the max/min scales to use in the computation, the number of output bins in the correlation function, the estimator to be used and information on the cosmology to be used for the coordinate transformation. The estimator selected in the configuration file defines the output product obtained.
