Abstract:
A sample of 18286 radio-loud active galactic nuclei (AGN) is
presented, constructed by combining the seventh data release of the
Sloan Digital Sky Survey with the NRAO (National Radio Astronomy
Observatory) VLA (Very Large Array) Sky Survey (NVSS) and the Faint
Images of the Radio Sky at Twenty centimetres (FIRST) survey. Using
this sample, the differences between radio galaxies of
"high-excitation" ("quasar-mode"; hereafter HERG) and
"low-excitation" ("radio-mode"; LERG) are investigated.

Note (1): Radio class as follows:
1 = single-component NVSS sources with a single FIRST match
2 = single-component NVSS sources resolved into multiple components by FIRST
3 = single-component NVSS sources without a FIRST counterpart
4 = sources are those which have multiple NVSS components
