        This data set contains Tracking and Navigation Files (TNF) created for
        the New Horizons Radio Science Experiment (REX) instrument during the
        Pluto Cruise mission phase.  The collection includes uplink tuning
        profile data in, and extracted from, Tracking and Navigation Files
        (TNFs) for all CORE observations.  Although uplink data signals were
        sent from the Ground Element to REX during the Approach sub-phase,
        tuning profiles for those signals are not provided as they are not
        needed to analyze those REX Approach observations comprising instrument
        checkout, characterization and calibration activities.
        
        During the PLUTO CRUISE mission phase, the New Horizons project performed
        a series of Annual CheckOuts (ACOs), designed to determine basic
        functionality and performance of the instrument complement. In addition,
        occultations of the Earth's moon were performed in May 2011 and January
        2012 (ACO-5 and ACO-6) to provide example data and experience in
        performing occultation inversion in preparation for the encounter at
        Pluto/Charon.
        
        These data were migrated from the previously released PDS3 data set
        NH-X-REX-2-PLUTOCRUISE-V2.0.
