TWO-POINT ANGULAR CORRELATION FUNCTION FOR THE GREEN BANK 4.85 GHZ SKY SURVEY

Abstract

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 $\ge$ 35 mJy over 20${}^{\circ }\le \delta <74^{\circ }$, 0${}^h\le \alpha <24^h$, and Galactic latitude $|b|\ge 10^{\circ }$. 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.
