. This quantity is the physical maximum velocity rotation corrected for inclination, expressed in km/s. It is deduced from the parameter vmaxg after correcting for inclination using incl . This rotation velocity is calculated from both the 21-cm line widths at different levels and/or the available rotation curves (generally H_alpha rotation curves). The rotation of the stellar component is given in the parameter vmaxs . HyperLeda . Questions: prugniel@obs.univ-lyon1.fr
