Galactic methanol masers at 6.6 GHz

Abstract

We have searched for 6.6-GHz methanol maser emission from the directions of more than 200 OH masers, together with a number of other sites of star formation. We have also observed previously reported methanol masers south of declination 24°. Where we detected methanol emission, we measured its position and have found more than 40 instances of small clusters of sources. We present observations of a total of 245 methanol masers with peak intensities ranging from 0.3 to 5000 Jy.
