Abstract:
We present an analysis of the relation between the star formation rate
(SFR) and mass of dense gas in Galactic clumps and nearby galaxies.
Using the bolometric luminosity as a measure of SFR and the molecular
line luminosity of HCO+ (3-2) as a measure of dense gas mass, we
find that the relation between SFR and Mdense is approximately linear.
This is similar to published results derived using HCN (1-0) as a
dense gas tracer.
Description:
Sixteen sources were mapped using the 10m Heinrich Hertz Telescope
(HHT) on Mount Graham, AZ. Observations were made on 2010 April 10 and
11 as well as 2010 May 4-9, excluding May 5.

Note (1): Comments:
IRDC = the source is associated with an infrared dark cloud. The near
kinematic distance was assigned.
Complex = the source is a part of a complex with a known distance. If one of
the kinematic distances was similar to the complex distance, that kinematic
distance was assigned (Mottram et al. 2010, Cat. J/A+A/510/A89).
