Description:
We examined all of the IRAS sources within the Five College Radio
Astronomy Observatory (FCRAO) Outer Galaxy Survey (OGS) region for
associated 12CO emission (as accounted for in the Brunt, Kerton, and
Pomerleau (2003, in press) catalogue of 12CO emission in the OGS).
Table 1 provides a ranked listing of IRAS-CO associations and Table 2
provides a listing of those IRAS sources with no CO associations. In
order to rank the various IRAS-CO associations we examined the
association of random lines of sight with CO emission in the OGS. The
resulting expectation numbers are provided to the reader in Table A1.
