SN01 was processed with IGS sites JAMA (Kingston, Jamaica) and RIOP (Riobamba, Ecuador) fixed using their ITRF (1/00) positions. Thus, baselines are thousands of kilometers long

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.
