KEPLER_VDISK

              KEPLER_VDISK is a variable that indicates the disk systemic veloc-
        ity  (in  km/s).   The value is always used to define the velocity field
        (see KEPLER_VELO result variable).

          However, for the radial profile, the usage depends on the /VSYSTEM op-
        tion.   When /VSYSTEM is not present, the radial profile is taken as the
        maximum brightness of the integrated, velocity aligned, spectrum for  at
        each radius. When /VSYSTEM option is present, the radial profile is tak-
        en at the velocity KEPLER_VDISK.
