Description
Summary:We present the galaxy two-point angular correlation function for galaxies selected from the seventh data release of the Sloan Digital Sky Survey (SDSS). The galaxy sample was selected with r-band apparent magnitudes between 17 and 21, and we measure the correlation function for the full sample as well as for the four magnitude ranges: 17-18, 18-19, 19-20 and 20-21. We update the flag criteria to select a clean galaxy catalogue and detail specific tests that we perform to characterize systematic effects, including the effects of seeing, Galactic extinction and the overall survey uniformity. Notably, we find that optimally we can use observed regions with seeing
