Notes. The heliocentric velocities derived from CO emission (Vhel,CO) are compared with those compiled by Oomen et al. (2018) (Vhel), and the residuals are defined as Vhel,CO - Vhel. The LSR velocities (VLSR) are included for reference. velocities are in km s−1 . The CO velocities can be found in this work and in Bujarrabal et al. (2013, 2016, 2017, 2018); Gallardo Cava et al. (2021).
