Detailed description of the data product¶

The configration product is neede to specify the ccompute Galaxy Clustering Power Spectrum, a Configuration file specifying the configuration is needed. The configuration file contain all the information about the max/min scale to use in the computation, the number of output bins in the output spectrum, the estimator to be used and information on the cosmology to be used for coordinate transformation. The estimator selected in the configuration file defines the output product obtained.
