OHANA, the AMBER/VLTI Snapshot Survey
  We report on the OHANA interferometric snapshot survey, carried out by the VLTI group at the Paranal observatory. It makes use of observing time not useful for any other scheduled scientific or technical tasks in the sense of a backup programme, to characterize the mass-loss for early-type stars. The survey employs the combination of AMBER's high spectral and spatial resolution. The spatially unresolved central object provides a reference frame for the fringe properties observed in the light of the continuum.
