V/18 Catalogue of Late-type Stars with Maser Emission (Engels, 1979)
================================================================================
Catalogue of Late-type Stars with OH, H2O or SiO Maser Emission

Abstract:
A catalog of more than 300 late type stars which display maser line
radio emission in OH, H2O or SiO molecules has been compiled. About
two thirds of the objects have been identified with optical or
infrared optics, mostly M-supergiants, Mira, or semiregular variables.
The catalog contains optical data such as spectral type, period and
magnitude, radio flux densities and velocities and infrared flux
densities in the region between 0.7 and 20 micrometers.
Introduction:
The systematic literature search is complete up to January 1, 1979.
The catalogue ends with a reference list containing all objects
followed by a code number and a list containing the literature
belonging to each code number. The literature cited for each object
contains all data used, except data from the general catalogue of
variable stars, the two-micron sky survey and the AFCRL infrared sky
survey. See the source reference for additional information.
The catalogued stars are divided in six groups
M-supergiant stars
Type I OH/IR stars
Type II OH/IR stars
H2O/IR stars without detected OH-emission
SiO/IR stars
Objects undetected in the optical or infrared
