General Location and Strategy: SN19 is placed in the moat to
the west of the sinuous ridge. We suspect it might be dropping down.

The first reported uncertainty uses the sigma of the coordinate group as a scaling factor and may be too pessimistic. The second uses the sigma of the single difference observations as a scaling factor and is obviously a gross underestimate.
