The rotation of the stellar component of galaxy is obtained from the compilation of internal stellar kinematics . The rotation of the gaseous component is given in the parameter vmaxg , and the stellar velocity dispersion in vdis . For disk-like galaxies (eg. mostly disks of spiral), the apparent rotation may be converted into the true (physical) rotation using the inclination given in the parameter incl . HyperLeda .
