NEW HORIZONS MVIC PLUTO CRUISE CALIBRATED V1.0

This is VERSION 1.0 of this data set. The spacecraft was in hibernation for much of the Pluto Cruise mission phase, and the focus for RALPH (MVIC and LEISA) during Annual CheckOuts one through four (ACO1-4) was preparation for the Pluto Encounter in 2015, including functional tests, and calibrations.

Science observations performed during this phase included Uranus and Neptune at phase angles (44 degrees and 34 degrees, respectively) not available from Earth (MVIC), calibrations with Neptune as a navigation test target (MVIC), Sun in the Solar Illumination Assembly (SIA) (MVIC and LEISA), the M6 and M7 clusters (MVIC), and other calibrations (stray light, dark, interference with other instruments).
