Abstract:
A summary of global properties and an evaluation of the equilibrium
state of molecular regions in the outer Galaxy are presented from the
decomposition of the Five College Radio Astronomy Observatory (FCRAO,
see 1998ApJS..115..241H 1998ApJS..115..241H) Outer Galaxy Survey and targeted 12CO and
13CO observations (at 115GHz) of four giant molecular cloud
complexes. The ensemble of identified objects includes both small,
isolated clouds and clumps within larger cloud complexes.
