This is VERSION 2.0 of this data set.                    SDC collected science data intermittently during the hibernation         years following the Jupiter encounter, designated as the PLUTOCRUISE     phase.  There were also Annual Checkouts (ACOs), STIM calibrations,      Noise calibrations, and an anomaly in November, 2007.                    SDC's main science data collection periods were during hibernation.      During ACOs, science data are taken intermittently but the user must     be careful in analyzing these data since there is usually more           activity on the spacecraft during hibernation.  STIM and Noise refer     to scheduled calibrations and are done with a regular cadence of one     per year after the Jupiter encounter; they occurred sporadically in      the early years of the mission.                                          Note that some SDC data files have the same stop and start time and      a zero exposure time.  The reason for this is that the start and         stop time for SDC data files are the event times for the first and       last events in the files, so for files that contain a single event,      these two values are the same.                                           The changes in Version 2.0 were re-running of the ancillary data         in the data product, updated geometry from newer SPICE kernels,          minor editing of the documentation, catalogs, etc., and resolution       of liens from the December, 2014 review, plus those from the May,        2016 review of the Pluto Encounter data sets.                            New observations added with this version (V2.0) include ongoing          cruise observations from August, 2014 through January, 2015.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.nh-x-sdc-2-plutocruise-v2.0_jumw-c67y", "issued": "2021-05-21", "keyword": ["dust", "new-horizons"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=NH-X-SDC-2-PLUTOCRUISE-V2.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "NEW HORIZONS                            \n      SDC PLUTO CRUISE                                                        \n      RAW V2.0"}
