Description

We report the results of a 22.2 GHz H2O line survey of all the known maser sources north of - 30 deg. Of the 509 sources observed, 203 were detected with an average detection limit of 9 Jy. The data are presented in an atlas and a table form and are intended to constitute an homogeneous reference data base for further study of the source variability. A brief description of the instrumentation is given. Comparison of the present results with those given in the literature indicates that most of the masers vary, with only 20% of the sources remaining constant, within the observational uncertainty
