This data set contains Raw data taken by the New Horizons Alice Ultraviolet Imaging Spectrograph instrument during the Pluto encounter mission phase. This is VERSION 2.0 of this data set. This data set contains ALICE observations taken during the the Approach (Jan-Jul, 2015) and Encounter mission sub-phases, including flyby observations taken on 14.July, 2015; the data are limited to those downlinked from the spacecraft as of the end of January, 2016. The rest of the downlinked data for this mission phase will be delivered in a future data set. Refer to the data set description above and the sequence table provided in the documentation for more detail about which observations are present in this data set. This is version 2.0 of this data set. Changes since version 1.0 include data downlinked between the end of July, 2015 and the end of January, 2016. These include Pluto and Charon occultations, Airglow observations during the weeks before and after the flyby, Approach VIS-UV and multi-maps, color and hi-resolution observations during the flyby, PEPSSI (plasma roll) and LORRI other ride-alongs, Also, updates were made to the documentation and catalog files, primarily to resolve liens from the V1.0 peer review.

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 1.0 of this data set.

Ground-based photometric observations of the 1985-1990 Pluto-Charon mutual events, observed from Palomar, Mauna Kea, and McDonald Observatories.

This data set contains Raw data taken by the New Horizons Radio Science Experiment (REX) instrument during the Pluto encounter mission phase. This is VERSION 1.0 of this data set. This REX dataset includes operational tests and calibrations taken during the approach to Pluto, including a series of ground in the loop tests to prepare for the Pluto and Charon occultations. From the day of the Pluto Encounter, two observations are included, the bi-static radar THERMSCAN data, which measured the DSN uplink signal reflected off of Pluto during the flyby, and the Pluto occultation data for both ingress and egress.

This data set contains Raw data taken by the New Horizons Alice Ultraviolet Imaging Spectrograph instrument during the Pluto encounter mission phase. This is VERSION 1.0 of this data set.

This data set contains Raw data taken by the New Horizons Long Range Reconnaissance Imager instrument during the Pluto encounter mission phase. This is VERSION 3.0 of this data set. 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.

This data set contains Calibrated data taken by the New Horizons Long Range Reconnaissance Imager instrument during the Pluto encounter mission phase. This is VERSION 2.0 of this data set. This data set contains LORRI observations taken during the the Approach (Jan-Jul, 2015) and Encounter mission sub-phases, including flyby observations taken on 14 July, 2015; the data are limited to those downlinked from the spacecraft as of the end of January, 2016. The rest of the downlinked data for this mission phase will be delivered in a future data set. Refer to the data set description above and the sequence table provided in the documentation for more detail about which observations are present in this data set. This is version 2.0 of this data set. Changes since version 1.0 include data downlinked between the end of July, 2015 and the end of January, 2016. These include Pluto Charon, Nix and Hydra observations from Approach, the day of the flyby, and Departure, lossless downlinks of images downlinked with lossy compression in version 1.0, Nix orbit determination observations, Multi-maps and VIS-UV maps taken in coordination with ALICE, High-phase and departure imaging, satellite photometry, non-critical navigation imaging, Kerberos and Styx imaging, KBO 1994 JR1 observations and departure ring-search observations taken in November, 2015, Charon dark side lit by Pluto-shine, and several other observations. 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. Also, updates were made to the documentation and catalog files, primarily to resolve liens from the V1.0 peer review.

This data set contains Raw data taken by the New Horizons Linear Etalon Imaging Spectral Array instrument during the Pluto encounter mission phase. This is VERSION 2.0 of this data set. This data set contains LEISA observations taken during the the Approach (Jan-Jul, 2015) and Encounter mission sub-phases, including flyby observations taken on 14.July, 2015; the data are limited to those downlinked from the spacecraft as of the end of January, 2016.

This is version 2.0 of this data set. Changes since version 1.0 include data downlinked between the end of July, 2015 and the end of January, 2016. These include Pluto observations around the time of the flyby, the Charon hi-resolution observations and co-observations with LORRI, Multi-map observations on 02.July, and Multi departure longitude observations. Also, updates were made to the documentation and catalog files, primarily to resolve liens from the V1.0 peer review.

Ground-based photometric observations of the 1985-1990 Pluto-Charon mutual events, observed from Palomar, Mauna Kea, and McDonald Observatories.

The dataset include simultaneous imaging obtained at the MMT in the infrared (H-band, 1.65 micron) and visible (unfiltered, approximately 0.24-1.24 micron) of Pluto occulting the star P445.3 (2UCAC 25823784) on 2007 March 18. The measurements included in the dataset were obtained continuously from 10:10:00 to 11:30:00 UTC. The midpoint of the occultation, at the MMT, was 10:53:49+/-00:01. The event was grazing and gives information about the atmosphere of Pluto to a depth of 1348 km above the surface. Images from the other observing sites for this event are not contained within this dataset, however lightcurve tables are included.
