摘要：

We have searched for 12-GHz methanol maser emission from the direction of 173 OH masers in star formation regions and obtained 53 detections, including 19 previously unreported. The observations of these and four other southern methanol masers are presented. We discuss some of the properties of this extensive uniform sample, in particular the presence of linear polarization and our discovery of intensity variations on a time-scale of weeks.
