›Measure Cosmological Parameters from the Large Scale Structure of the Galaxy Clustering
Galaxy clustering data can be used to measure the cosmic expansion history H(z),
the angular-diameter distance DA(z), the linear redshift-space distortion parameter,
and the physical matter density. Here we present a method for using effective
multipoles of the galaxy two-point correlation function to measure these parameters,
and validate it using LasDamas mock galaxy catalogs. Our definition of effective
multipoles explicitly incorporates the discreteness of measurements, and treats
the measured correlation function and its theoretical model on the same footing.
