Scientific paper

The results of a search for water masers using newly available, accurate positions of the sources in the two-Micron Sky Survey are presented. A total of 455 IRC sources were searched, and 40 masers were detected, with probably 28 being detected for the first time. The total detection rate is 8.8 percent and is only weakly correlated with the K magnitude, indicating that the 2.2 micron flux is not the determining parameter for the existence of a maser. The flux at some other wavelength or the temperature and density within the circumstellar environment must be more important. No difference between the galactic distribution of masing and nonmasing IRC sources is indicated.
