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.
