      <description>New large-scale CO surveys of the first and second Galactic quadrants and the 
nearby molecular cloud complexes in Orion and Taurus, obtained with the 
Harvard-Smithsonian Center for Astrophysics 1.2 m telescope, have been 
combined with 31 other surveys obtained over the past two decades with that 
instrument and a similar telescope on Cerro Tololo in Chile, to produce a 
new composite CO survey of the entire Milky Way. The survey consists of 
488,000 spectra that Nyquist or beamwidth (1/8 deg) sample the entire Galactic 
plane over a strip 4 deg-10 deg wide in latitude, and beamwidth or 1/4 deg sample 
nearly all large local clouds at higher latitudes. Compared with the previous 
composite CO survey of Dame et al. (1987), the new survey has 16 times more 
spectra, up to 3.4 times higher angular resolution, and up to 10 times higher 
sensitivity per unit solid angle. 
&lt;P&gt;
Users should be aware that both the angular resolution and the 
sensitivity varies from region to region in the velocity-integrated map.
The component surveys were integrated individually using clipping or 
moment masking in order to display nearly all statistically significant 
emission but little noise above a level of ~1.5 K km/s. See the reference 
below and the

Millimeter-Wave Group site&lt;/a&gt; for  more details  Provenance:  Data taken by two nearly-identical 1.2 m 
       telescopes in Cambridge, MA and on Cerro Tololo, Chile  combined into a 
       complete survey of the Milky Way with CO integrated over all velocities.. This is a service of NASA HEASARC.
