Angular and threedimensional correlation functions determined from the Muenster Red Sky Survey
Abstract
We measure the twodimensional galaxygalaxy correlation function from the Muenster Red Sky Survey. This survey covers a slightly larger sky area compared with the APM survey and is complete to r_{F}<18.3mag (z_{med}~0.14). The large dynamic range of the survey makes it possible to examine subcatalogues with different limiting magnitudes. The positive parts of our measured angular correlation functions (after the colour correction) show excellent agreement with those measured by Maddox, Efstathiou & Sutherland from the APM galaxy catalogue. From the measured angular correlation functions, the threedimensional twopoint correlation function ξ(r) is calculated. We have chosen the evolution parameter ∊ so that the change of the correlation length r_{0} with the depth of the subcatalogue is minimal. This prescription gives r_{0}=5.82+/0.05h^{1}Mpc and a very high, positive evolution parameter ∊=2.6. The position of the point where the threedimensional correlation function breaks away from the power law depends on the depth of the subcatalogues: the break comes earlier for lower magnitude limits, and later for higher magnitude limits.
