New Horizons Alice Ultraviolet Imaging Spectrograph Data Archive Bundle This bundle contains the following collections: New Horizons Alice data collections, one for each mission phase and processing level (raw and calibrated). In general these will contain 2D spectral arrays, 1D data arrays and binary housekeeping tables in the .FIT format from the Alice instrument. Reference Files Used in Calibrating Data from the New Horizons Alice Instrument contains a cumulative set of ancillary files (dark, effective area, wavelength, flat) used in calibrating the data sets delivered by the Alice instrument over the course of the New Horizons primary and extended missions. See each collection's overview file for further details. This bundle was created by the Small Bodies Node (SBN) of the Planetary Data System (PDS) as part of migration from PDS3 to PDS4. The data collections from the prime mission and KEM1 extended mission found in this bundle were originally migrated from PDS3 datasets produced by the New Horizons SOC. All other extended mission data is produced by the New Horizons SOC using the PDS4 standards.
