						Oxide Abundance Data September 19, 2016.
						 PDS release 49 
						includes APXS Oxide Abundance data for Opportunity sols 
						1 through 4000, updating the previous delivery from 
						2012.  This data set contains oxide abundance 
						data derived from the APXS Reduced Data Record (RDR) 
						products acquired by the Alpha Particle X-ray 
						Spectrometers on both MER rovers. The data were provided by 
						Ralf Gellert, University of Guelph, and Rudolph Rieder, 
						Max Planck Institute, and archived by the PDS 
                        Geosciences Node.
