Description:
    High sensitivity observations of the 22GHz water maser emission have
    been carried out with the Effelsberg 100m radio telescope. The
    observed sample was 79 candidate high-mass protostellar objects from a
    flux-limited sample of 6.7GHz methanol sources (Szymczak et al.,
    2002A&A...392..277S). Water maser emission was found in 41 sources of
    which 28 were not previously catalogued.
