We quantify the angular clustering of radio galaxies in the NVSS and FIRST surveys using the two-point correlation function and the moments of counts-in-cells – both important points of comparison with theory .
These investigations consistently demonstrate that the slope of the correlation function for radio galaxies agrees with that for optically-selected galaxies , \gamma \approx 1.8 .
We describe how to disentangle the imprint of galaxy clustering from the two observational problems : resolution of radio galaxies into multiple components and gradients in source surface density induced by difficulties in processing “ snapshot ” radio observations ( significant in both surveys below S _ { 1.4 GHz } \sim 15 mJy ) .
This study disagrees in some respects with previous analyses of the angular clustering of radio galaxies .
