Query: G343.1-2.3 and PSR 1706-44   The association of G343.1-2.3 and PSR 1706-44 has been controversial from its
first proposal. In this paper we present new evidence from images made by with
the Australia Telescope Compact Array (ATCA), MRT and Mt. Pleasant. To cover
the full extent of G343.1-2.3 with ATCA mosaicing was required, and we present
the polarisation images from this experiment. The ATCA observations confirms
the much larger extent of the SNR, which now encompasses the pulsar.
