Abstract

We have observed 22 OH masers and associated continuum sources with the VLA at λ 18 cm, and deduce that type I masers are always associated with ultracompact continuum sources, while type II(a) (1720 MHz) masers probably never are. Implications for the type of pumping for each category of maser are discussed.
