摘要
The Molonglo Observatory Synthesis Telescope (MOST) has been used recently to make a new survey of the Galactic Centre region at 843 MHz, spanning Galactic longitudes 1=335 degrees-360 degrees-5 degrees and Galactic latitudes in the range \b\<2.degrees 5. The resolution of the MOST at the declination of the Galactic Centre (delta = - 29 degrees) is 90 x 43.5 arcsec(2) and the sensitivity is similar to 5 mTy beam(-1) (dynamic-range-limited). The survey presents an unprecedented vista of the Galactic Centre and inner Galactic plane at a frequency near 1 GHz. This paper gives general discussions of some of the preliminary results of this survey, including wide-field images of the Galactic Centre region. Further papers will discuss specific results of the survey in detail.
