Comments

This is the single survey with the largest angular extent, covering more than the entire second quadrant over a wide latitude range. The sampling is 1/4°. Spectra spaced every 1/4° were extracted from the Cygnus, CasA, and MonOB1 surveys and included in the cubes presented here. All the spectra were interpolated to a channel spacing of exactly 1.300 km/s (in contrast to many other surveys that have a spacing of 1.3004 km/s, corresponding to 0.5 MHz at the CO frequency).
