Northern Sky Survey

After completion of Dame, Hartmann & Thaddeus (2001), the CfA 1.2 m telescope continued mapping the sky to ever greater angles from the Galactic plane, eventually reaching the north Galactic pole and our southern declination limit of -17°. In Dame & Thaddeus (2022), all of this new data were combined with the 2001 survey to produce the first complete CO survey of the entire northern sky.

Here we provide the 5 FITS data cubes described in Section 5 of Dame & Thaddeus (2022). Table 3 from that paper is reproduced here:
