Description
Version 3.0 of the calibrated data set from the New Horizons spacecraft's Linear Etalon Imaging Spectral Array (LEISA) instrument during the Pluto encounter phase. The data includes observations from the Approach (January-July 2015), Encounter, Departure, and Transition sub-phases, completing all Pluto mission phase deliveries for LEISA. Updates include data downlinked through late October 2016, multi-map approach observations, moon observations, high-resolution departure data, and calibration campaign tests.
Use Cases
Analyze surface composition of Pluto and its moons based on spectral imagery data.
Calibrate remote sensing instruments using the included calibration campaign test data.
Study temporal changes on Pluto using multi-map observations from the Approach phase.
Validate spectral data processing pipelines using the updated calibration files and full-frame products.
Strengths
Completes the delivery of all LEISA data covering the Pluto Encounter and subsequent Calibration Campaign.
Includes high-resolution departure observations and functional calibration tests like scans across the detector of Arcturus.
Data were re-run through the pipeline with updated calibration files, affecting all calibrated data products.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and file size are unknown, which may limit suitability assessment.
