Abstract:
New James Clerk Maxwell Telescope (JCMT) HARP CO 3-2 observations of
the W5 star forming complex are presented, totalling an area of
∼12000-arcmin2 with sensitivity better than 0.1K per 0.4km/s
channel. We discovered 55 CO outflow candidates, of which 40 are
associated with W5 and 15 are more distant than the Perseus arm.
Description:
CO J=3-2 345.79599 GHz data were acquired at the 15-m James Clerk
Maxwell Telescope (JCMT) using the HARP array on a series of observing
runs in 2008.

Note on table3.dat: Derived properties of the outflows in the optically thin
limit. Typical optical depth corrections for 12CO3-2 are in the range 7-14
(Curtis et al. 2010MNRAS.408.1516C 2010MNRAS.408.1516C). The correction for velocity confusion
is ≳2 but poorly constrained (Arce et al. 2010ApJ...715.1170A 2010ApJ...715.1170A). Finally,
an excitation correction in the range 1-20 is likely required as described
in the Appendix. The mass and momentum values can be multiplied by these
factors to acquire the corrected values. The energy is weighted more
heavily towards high-velocity, low-optical-depth gas, so the correction
factor is likely to be lower.
