Query: 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.
