The New Horizons Pluto Encounter Surface Composition data set contains map data from the Multispectral Visible Imaging Camera instrument and the Linear Etalon Imaging Spectral Array instrument on New Horizons during the Pluto encounter mission phase. Color, albedo, and absorption map data products are included for the CH4, N2, CO, and H2O species. This is VERSION 1.0 of this data set.

This data set contains Calibrated data taken by the New Horizons Multispectral Visible Imaging Camera instrument during the Pluto encounter mission phase. This is VERSION 3.0 of this data set. This data set contains MVIC observations taken during the the Approach (Jan-Jul, 2015), Encounter, Departure, and Transition mission sub-phases, including flyby observations taken on 14 July, 2015, and departure and calibration data through late October, 2016. This data set completes the Pluto mission phase deliveries for MVIC. This is version 3.0 of this dataset. Changes since version 2.0 include the addition of data downlinked between the end of January, 2016 and the end of October, 2016, completing the delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. It includes multi- map observations from the Approach phase, observations of the moons, hi- res, full-frame observations from Pluto Encounter and Departure, and ring search observations. There may be some overlap between prior datasets and this dataset, due to only partial, windowed, or lossy data in prior datasets. This dataset also includes functional tests from the Calibration Campaign, including calibration observations of the M6 and M7 clusters, and HD205905. Also, updates were made to the calibration files, documentation, and catalog files. For any data previously delivered as sub-frame windows, this delivery will fill in the image data outside those windows. Changes to the calibration involved only changes to the spectrum-specific calibration constants provided in FITS headers and in PDS labels; the calibrated Data Number values in the calibrated data set, excluding image data outside the sub-frame windows mentioned above, will not be substantively changed.

This data set contains Raw data taken by the New Horizons Multispectral Visible Imaging Camera instrument during the Pluto encounter mission phase. This is VERSION 2.0 of this data set. This data set contains MVIC observations taken during the the Approach (Jan-Jul, 2015) and Encounter mission sub-phases, including flyby observations taken on 14 July, 2015. This is version 2.0 of this data set. Version 1.0 included data downlinked between the end of July, 2015 through the end of October 2015. Changes since version 1.0 include additional data downlinked between October, 2015 and the end of January, 2016. These observations include Charon, Nix and Hydra observations from the day of encounter, Pluto and Charon Multi-maps and Multi-longitudes from Approach, full-frame versions of observations downlinked as sub-framed (windowed) versions for version 1.0, Kerberos and Styx observations, Pluto High-phase and Color observations, and departure Ring-search observations taken in November, 2015. Also, updates were made to the documentation and catalog files, primarily to resolve liens from the V1.0 peer review.

This data set includes the complete set of New Horizons (NH) SPICE data files (``kernel files''), which can be accessed using SPICE software. The SPICE data contain geometric and other ancillary information needed to recover the full value of the science instrument data. In particular SPICE kernels provide spacecraft and planetary ephemerides, instrument mounting alignments, spacecraft orientation, and data needed for relevant time conversions.

This data set contains Calibrated data taken by the New Horizons Linear Etalon Imaging Spectral Array instrument during the Pluto encounter mission phase. This is VERSION 3.0 of this data set. This data set contains LEISA observations taken during the the Approach (Jan-Jul, 2015), Encounter, Departure, and Transition mission sub-phases, including flyby observations taken on 14 July, 2015, and departure and calibration data through late October, 2016. This data set completes the Pluto mission phase deliveries for LEISA. This is version 3.0 of this dataset. Changes since version 2.0 include the addition of data downlinked between the end of January, 2016 and the end of October, 2016, completing the delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. It includes multi- map observations from the Approach phase, observations of the moons, and hi-res departure observations. It also includes functional tests from the Calibration Campaign including scans across the detector of Arcturus, and a second test of the Solar Illumination Assembly. Updates were made to the calibration files, documentation, and catalog files. The data were re-run through the pipeline, which changes the FITS headers of the raw files, but not the FITS data. The exceptions to that are products for which only sub-frame windows were downlinked in previous versions of this data set: those products have been re-downlinked either in full, or all regions outside the previously downloaded windows were downloaded and merged to form full-frame products. In so doing, some LEISA products have more frames downloaded, resulting in a change in the BANDS keyword value in PDS labels. Finally, the updated calibration files cause changes to all of the calibrated data.

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).

This data set contains LORRI observations taken during the the Approach (Jan-Jul, 2015), Encounter, Departure, and Transition mission sub-phases, including flyby observations taken on 14 July, 2015, and departure and calibration data through late October, 2016. Departure observations include a ring search of the Pluto system and 1994 JR1 observations. This data set completes the Pluto mission phase deliveries for LORRI. This is version 3.0 of this dataset. Changes since version 2.0 include the addition of data downlinked between the end of January, 2016 and the end of October, 2016, completing the delivery of all data covering the Pluto Encounter and subsequent Calibration Campaign. It includes multi- map observations from the Approach phase, observations of the moons, hi- res, full-frame observations from Pluto Encounter and Departure, sliver maps, and ring search observations. There may be some overlap between prior datasets and this dataset, due to only partial, windowed, or lossy data in prior datasets. Observations at closest approach to Pluto are marked with _CA in the Request ID. This dataset also includes functional tests from the Calibration Campaign, including a regular observation of NGC3532. Finally it includes the first set of distant KBO observations. Also, updates were made to the calibration files, documentation, and catalog files. There were minor changes to the level 2 LORRI calibration process, as well as to the LORRI calibration constants for the final Pluto P3 PDS delivery. The process change involves gap removal during calibration. Files with gaps come in many flavors, depending on where the gap lies within the image. This update recognizes some additional possiblities, mainly that the gap might be close to the bottom or top of the image (and therefore the previous algorithm would fail because it filled the gap with median pixel info from both above and below the gap). The new algorithm will take the info from one side of the gap exclusively, when appropriate.
