    dct:description "Archival Tracking Data Files (ATDFs, also sometimes known as TRK-2-25 data) from the MAGELLAN mission to Venus (1989-1994) and Orbit Data Files (ODFs, also known as TRK-2-18 data) from the final 2-3 years of the MAGELLAN mission (1992-1994). These data include range and Doppler measurements from the radio tracking system of the NASA Deep Space Network (DSN).  The measurements can be used to derive a spherical harmonic model of the Venus gravity field." ;
