摘要
We have just completed the observational stage of a 2.4 GHz survey of the Southern Galactic Plane, using the Parkes radiotelescope, between 238 degrees less than or equal to l less than or equal to 365 degrees and with a latitude range of at least \b\ less than or equal to 5 degrees (beamwidth similar to 9 arcmin). The survey details both continuum emission and linear polarisation down to rms noises of approximately 12 and 4 mJy/beam respectively. It is the most sensitive survey to date of the southern plane at this frequency and should nicely complement the Effelsberg northern plane surveys in addition to the recent southern surveys such as the 843 MHz MOST survey and the 5 GHz PMN survey. The total-power maps are now completed, and reduction of the polarisation data is still in progress. In addition to compact HII regions and extragalactic sources, we are detecting on our total-power images a considerable amount of large-scale structure, and a significant number of new SNR candidates and spur-like features.
