Abstract:
We report results of the first phase of observations with Australia
Telescope Compact Array (ATCA) at 5 and 9GHz of the fields around 411
γ-ray sources with declinations less than +10° detected with
Fermi but marked as unassociated in the 2FGL catalogue. We have
detected 424 sources with flux densities in a range of 2mJy to 6Jy
in the fields of 283 γ-ray sources within their position error
ellipses drawn to cover the area of 99 per cent probability of their
localisation. Of them, 146 objects were detected in both bands. We
found 84 sources with spectral index flatter than -0.5 in our sample.
The majority of detected sources are weaker than 100 mJy and for this
reason were not found in previous surveys. Approximately 1/3 of our
sample, 128 objects, have the probability of being associated by more
than 10 times than the probability of being a background source found
in the vicinity of a γ-ray object by chance. We present the
catalogue of positions of these sources, estimates of their flux
densities and spectral indices when available.
Description:
Table S1: catalogue of 146 objects detected at both 5 and 9GHz
sub-bands of 2FGL sources marked as unassociated within the ellipse of
99% probability of their localization
Table S2: catalogue of 229 objects detected only at 5GHz sub-band
within the ellipses of 99% probability of localisation of Fermi
sources marked as unassociated in 2FGL catalogue.
Table S3: catalogue of 49 objects detected at sidelobes of either 5 or
9GHz beam within the ellipses of 99% probability of localisation of
Fermi sources marked as unassociated in 2FGL catalogue.

Global notes:
Note (G1): Flag as follows:
a = a source is high confidence: it has likelihood ratio greater than 10
e = a source was found in a field of extended objects
f = a source has spectral index flatter than -0.5 between 5 and 9GHz
Note (G2): Matching 1GHz catalogue label:
N = NVSS, Condon et al., 1998, Cat. VIII/65
M = MGPS-2, Murphy et al., 2007, Cat. VIII/82
S = SUMSS, Mauch et al., 2008, Cat. VIII/81
Note (G3): Fillvalue -9.9 means no information about this parameter is available
