Abstract:
We test the prediction of Hamilton and Helfand (1993ApJ...418...55H 1993ApJ...418...55H)
that faint radio selected galaxies are a new class contributing to the
diffuse X-ray background (XRB) radiation. The test is based on the
correlation of X-ray, optical and radio positions for sources detected
in ROSAT (S0.08-2.4keV>6x10-15erg/s/cm2, 69 sources) and ATCA
(S1.42GHz>250uJy, 93 sources) observations of the Einstein Pavo
field. A total of six ATCA radio sources inside the inner ring of the
ROSAT image are located within 10" of the ROSAT X-ray positions, with
one associated by random chance.

Note (1): Notes as follows:
) = sources which are found to be below 3σ rms and for these
sources the maximal pixel value were estimated within area of source
+ = sources found to be between 3 and 5σ rms
Note (2): Spectral indexes are calculated if at least three (two if well
separated in frequency) measurements above 5σ rms are available
for the source. The index is such that S(ν)∝να
