1. The discovery was made by making high-precision radial velocity measurements with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph.

2. A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae.

3. However, this was ruled out by means of more accurate radial velocity measurements.

4. If the orbit is almost face-on, especially for superjovians detected by radial velocity, then those objects may actually be brown dwarfs or even red dwarfs.

5. Axial velocity presents a saddle-shaped distribution, and with a good axial symmetry except the inlet position. Radial velocity is less an order of magnitude with a non-axisymmetric distribution.

6. In between, we use the minimum of the Azimuthally and temporally averaged axial profile of the radial velocity as the location of the vortex inflow and correspondingly, the location of the vortex outflow is obtained with its maximum
