Description:
This survey consists of CO(J=1-0) (115 GHz) spectra for the entire
Galactic plane. The latitude coverage varies with longitude and in
some regions extends from -25 degrees to +25 degrees. The observations
were made with the Columbia/GISS 1.2m telescope in New York City, and
a twin telescope on Cerro Tololo in Chile. The angular resolution of
the survey is 30' (square), the velocity resolution is 1.3km/s and
the sensitivity ranges from about 0.1K/chan to 0.35K/chan. The
survey is presented as 720 latitude-velocity maps in FITS format,
one for each 30' of longitude from -180.0 deg to +179.5 deg, and one
velocity-integrated map covering the entire plane. The velocity range
of each file is -300 km/s to +300 km/s. The survey has been updated
to include some additional data, more careful reprojections of the
regions that were originally mapped in equatorial coordinates, and
improved estimates of the absolute calibration of the CO intensities
(Digel and Dame 1995, unpublished).
