摘要:

我们提出了第四部分的银河平面调查甲醇脉泽在6668兆赫,跨越经度范围186度至330度。我们报告207脉泽检测,89新的调查。这完成了甲醇多波束调查的南部天空部分,包括很大比例的新来源,43%。我们还包括猎户座麒麟星形成区域的盲观测结果,正式的甲醇多波束调查的纬度范围之外,只有四个以前已知的甲醇发射站点被检测到,其中我们提出了新的位置和光谱的脉泽猎户座-A(南)和猎户座-B,获得与MERLIN阵列。

英文摘要:

We present the fourth portion of a Galactic Plane survey of methanol masers at 6668 MHz, spanning the longitude range 186 degrees to 330 degrees. We report 207 maser detections, 89 new to the survey. This completes the southern sky part of the Methanol Multibeam survey and includes a large proportion of new sources, 43%. We also include results from blind observations of the Orion-Monoceros star forming region, formally outside the latitude range of the Methanol Multibeam survey; only the four previously known methanol emitting sites were detected, of which we present new positions and spectra for masers at Orion-A (south) and Orion-B, obtained with the MERLIN array.
