Abstract:
We have carried out extensive radio and optical follow-up of 176
sources from the 15-GHz 9th Cambridge survey. Optical identifications
have been found for 155 of the radio sources; optical images are given
with radio maps overlaid. The continuum radio spectrum of each source
spanning the frequency range 1.4-43GHz is also given.
Description:
Simultaneous continuum snapshot observations were made for each source
at frequencies of 1.4, 4.8, 22 and 43GHz with the VLA of the National
Radio Astronomy Observatory and at 15GHz with the Ryle Telescope. In
addition, 51 sources from the 00h field were observed within a few
months at 31 GHz with the Owens Valley Radio Observatory (OVRO) 40-m
telescope.

Note (4): Optical types as follows:
G = extended, elliptical type objects
G+ = those with irregular morphology
Q? = unresolved optical counterparts with O-R<1.6
G? = unresolved optical counterparts as point-like objects with
O-R≥1.6, or not definitely less than 1.6
The two sources 9CJ0030+2809 and 9CJ0958+2948 are elliptical but also
have near neighbours, and are labelled 'G'.
