Mean gradient of velocities for different bins of log Σgas.
|log Σgas (M⊙ pc−2)||log Σgas,mean||Mean Vshear (km s−1 kpc−1)|
|− 0.67 − 0.33||− 0.41||22.72|
|− 0.33–0.00||− 0.17||28.44|
Notes. The values of Σgas used to define these bins are mass-weighted averages whereas Σgas,mean is the usual surface-weighted average. The mean Vshear is mass-weighted. As can be seen, higher Vshear are bound towards higher Σgas. Section 4 gives more details.
