Galactic water vapor emission: further observations of variability
Authors:Knowles S H  Mayer C H  Sullivan W T  Cheung A C
Abstract:Recent observations of the 1.35-centimeter line emission of water vapor from galactic sources show short-term variability in the spectra of several sources. Two additional sources, Cygnus 1 and NGC 6334N, have been observed, and the spectra of W49 and VY Canis Majoris were measured over a wider range of radial velocity.
