                The Magellan ARCDR Ephemeris Parameters file is a CSV-format text file that 
                contains information about Magellan orbits when altimetry and radiometry
                data were being collected. These parameters are taken from the PDS3 labels
                of the ephemeris files in the original ARCDR dataset. The ephemeris files
                are not included in this archive because they duplicate the data stored at
                the NAIF node of PDS.
