Abstract (from CDS):

We present the results of a high sensitivity survey for 6.7GHz methanol masers towards 22GHz water masers using the 100m Efflesberg telescope. A total of 89 sources were observed and 10 new methanol masers were detected. The new detections are relatively faint with peak flux densities of between 0.5 and 4.0Jy. A nil detection rate from low-mass star forming regions enhances the conclusion that the masers are only associated with massive star formation. Even the faintest methanol maser in our survey, with a luminosity of 1.1x10^–9L_☉, is associated with massive stars, as inferred from its infrared luminosity.
