MPF ROVER MARS ALPHA PROTON X-RAY SPECTROMETER EDR V1.0

The APXS EDRs are a collection of 27 measurements (173 data files) obtained by the Alpha Proton X-ray Spectrometer (APXS). Of these, nine are measurements of rock, seven are of soil (if Scooby Doo is an indurated soil rather than a rock), and eleven are of atmosphere. The atmosphere was measured on Sol 1 to determine background cosmic ray levels, on a few occasions for electronics noise tests, and sometimes as a result of the APXS deployment mechanism not reaching the intended rock surface.
