We present the results of a continuum snapshot survey
of a region of the Large Magellanic Cloud
including the area of the giant molecular cloud and the 30 Doradus nebula.
The observations have been carried out with the Australia Telescope
Compact Array (ATCA)
at 1.4 and 2.4 GHz.
Most fields are complete to about 6 mJy peak flux density at 1.4 GHz and
to about 3 mJy at 2.4 GHz. The positions, peak and integral
flux densities of 113 compact (
) sources
detected at 1.4 GHz and of 70 sources (
) detected at 2.4 GHz
are presented. Positions are accurate to about 3″ and peak flux
densities are accurate to about 10% or better, depending on the source
position relative to the pointing centers. 32 of the sources detected
at 1.4 GHz are coincident with Hα objects in the catalogue of
Davies et al.; these are possibly intrinsic to the LMC.
However, we suppose that most are background objects, since the
number vs. flux agrees with predictions of extragalactic source counts
from other surveys.
