New Horizons LORRI Pluto Cruise Raw Data v2.0


Abstract: This data set contains Raw data taken by the New Horizons Long Range Reconnaissance Imager instrument during the pluto cruise mission phase. This is VERSION 2.0 of this data set. The spacecraft was in hibernation for much of the Pluto Cruise mission phase, and the focus for LORRI during Annual CheckOuts (ACOs) one through four (ACO1-4) was preparation for the Pluto Encounter in 2015, including functional tests, calibrations, and encounter rehearsals. Science observations performed by LORRI during this phase included the following targets: KBO objects KBO 2005 FY9 (Makemake) and KBO 2003 EL61 (Haumea); Centaur object Chariklo; the planets Jupiter, Uranus, and Neptune. The ACO tests also had LORRI observing several other targets: Pluto; the star field that will be visible 3 days before Pluto closest approach in 2015; the M7 star field; the star Vega. A full functional test was performed during ACO1 in 2007, with ACO 'Lite' tests performed during ACO2-4 in 2008, 2009 and 2010. Specific tests and calibrations performed during ACOs included the following: scattered light test (2007, 2008, 2010); Pluto OpNav test (2007, 2008); lamp tests (2007, 2008, 2009, 2010); star tracker calibration test (2008); GNC mosaic settling test (2008); LEISA-LORRI ridealong (2008); scattered light dither test (2010). 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. The lossy images from Version 1.0 were recalibrated, including expanding the 'bad' pixel designation of 8x8 boxes affected by the first 34 pixels of header information in the calibrated quality map. No new observations were added with this version (V2.0).
