Two-Point Angular Correlation Function for the Green Bank 4.85 GHz Sky Survey

This paper presents an angular correlation analysis of the Green Bank 4.85 GHz radio catalog (Gregory & Condon 1991) of 54,579 sources (S gsim 25 mJy). The Green Bank catalog is found to be complete to S $geq$ 35 mJy over 20$^{circ} leq delta < 74^{circ}$, 0$^h leq alpha < 24^h$, and Galactic latitude $|b| geq 10^{circ}$. The 2-point angular correlation function shows evidence for the clustering of radio sources, with a power-law distribution consistent with a slope $gamma = -0.8$. This may well provide the $first$ detection of an angular correlation in a large area, complete deep radio survey.
