NEW HORIZONS SDC POST-LAUNCH CHECKOUT CALIBRATED V4.0

This data set contains Calibrated data taken by the New Horizons Student Dust Counter instrument during the post-launch checkout mission phase. This is VERSION 4.0 of this data set. The SDC instrument was commissioned on March 2, 2006 and stepped through a checkout of all instrument functionality successfully. Following these activities, SDC collected science data intermittently throughout the first year of the mission. The changes in Version 4.0 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. No new observations were added with Version 4.0.
