The coverage extension was carried out with the same telescope as was used for the plane survey, the CfA 1.2 m, and perfectly meshes with its irregular boundaries in latitude. The merged survey is released by the authors in the form of CO line spectral data cubes. To create the LAMBDA map, the moment-masked data cube for the combined survey was integrated over +/- 36 km/sec, the full range over which significant emission is detected (see Figure 8 of Dame & Thaddeus 2022; the combined survey does not include the high-velocity observations available from the Dame, Hartmann & Thaddeus 2001 data). The velocity integrated brightness temperature map was then interpolated from the original rectilinear projection onto pixel centers appropriate for HEALPix Nside=256. The LAMBDA map is in units of K-km/sec, and a mask is provided indicating those portions of the sky that are unobserved.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).
