A Survey for H2O Megamasers III. Monitoring Water Vapor Masers in Active Galaxies

Autor: Braatz, J. A., Wilson, A. S., Henkel, C., Gough, R., Sinclair, M.

We present single-dish monitoring of the spectra of 13 extragalactic water megamasers taken over a period of 9 years and a single epoch of sensitive spectra for 7 others. Our data include the first K-band science observations taken with the new 100 m
