Abstract:
We present the 100 strongest 1.4GHz point sources from a new mosaic
image in the direction of the Large Magellanic Cloud (LMC). The
observations making up the mosaic were made using Australia Telescope
Compact Array (ATCA) over a ten year period and were combined with
Parkes single dish data at 1.4GHz to complete the image for short
spacing. An initial list of co-identifications within 1000 at 0.843,
4.8 and 8.6GHz consisted of 2682 sources. Elimination of extended
objects and artifact noise allowed the creation of a refined list
containing 1988 point sources.
Description:
During October 1994 and February 1995, the LMC was surveyed in mosaic
mode, centred at 1.4GHz (bandwidth 128MHz), using the Australia
Telescope Compact Array (ATCA). This survey divided the LMC into 12
regions, each containing 112 pointing centres. Each pointing centre
was observed approximately 115 times (ranging from 95 to 140) for 15s.
