VizieR Online Data Catalog: A CO survey of the entire northern sky (Dame+, 2022)

The 1.2m Millimeter-Wave Telescope at the Center for Astrophysics (CfA)| Harvard & Smithsonian has been observing the J=1-0 rotational transition of interstellar carbon monoxide for nearly 50yr.

A map of velocity-integrated CO intensity over the entire northern sky is shown in Figure 8. We have partitioned the emission in Figure 8 into 198 discrete high-latitude clouds (|b|>20°) and list their properties in Table 2. Here we define clouds as regions of contiguous emission. See Section 4.

All 382,202 CO(1-0) spectra are made available in a single FITS-format data cube. In Table 3 we list five versions of the cube that are publicly available. All of the cubes are on a rectangular Cartesian grid of velocity, longitude, and latitude. See Section 5.
