This survey contains data from the composite CO map constructed by Dame, Hartmann and Thaddeus (2001) from 37 individual surveys of the Galaxy in the CO (1-0) line. Due to the composite nature of the map and processing used to render a uniform S/N appearance, the user is cautioned that angular resolution and sensitivity vary across the map. Survey data are limited to Galactic latitudes |b|%3C32 deg., with roughly half of that area containing observations.To create this file, the velocity-integrated brightness temperature map, W(CO), was obtained from the CfA Millimeter Wave Group website and then interpolated onto a HEALPix grid with Nside. Original acknowledgement for data: We acknowledge the use of the Legacy Archive for Microwave Background Data Analysis (LAMBDA), part of the High Energy Astrophysics Science Archive Center (HEASARC). HEASARC/LAMBDA is a service of the Astrophysics Science Division at the NASA Goddard Space Flight Center."
