... Optical Counterparts for 70,000 Radio Sources: APM Identifications for the FIRST Radio Survey . ... We describe a program to identify optical counterparts to radio sources from the VLA FIRST survey using the Cambridge APM scans of the POSS-I plates. We use radio observations covering 4150 square degrees of the north Galactic cap to a 20 cm flux density threshold of 1.0 mJy; the 382,892 sources detected all have positional uncertainties of Format for the Table of FIRST-APM Optical Counterparts . ...

For each filter there is a column for the parameterisation of the shapes of the sources (ie the semi-major, semi-minor axes and position-angle of the major axis). These values are the averaged values from the individual sources that were merged into a source. There are also columns giving the mean parameters for each source, which have been computed from the mean values for each filter. ...
