New Horizons Solar Wind Around Pluto (SWAP) - Pluto Encounter Raw Data, Version 1.0

This data set contains Raw data taken by the New Horizons
Solar Wind Around Pluto (SWAP) instrument during the PLUTO ENCOUNTER mission phase.
These data were migrated from the PDS3 dataset: NH-P-SWAP-2-PLUTO-V3.0.

SWAP comprises electro-optics and detectors to obtain count rate
measurements of the solar wind; measuring the solar wind before,
during and after the Pluto encounter will allow characterization
of the atmospheric escape rate of Pluto. The SWAP electro-optic
elements select the angles and energies of the solar wind and
pickup ions to be measured; ions thus selected are registered with
a coincidence detector system. SWAP measures the energy spectrum
of ions in its environment by varying (also called scanning or
sweeping) voltages of the electro-optics over many steps during a
short time period. SWAP can also immediately follow a sweep of
coarse voltage steps with a sweep of finer steps, centered on the
peak measurement of the coarse sweep, to obtain a higher
resolution of that portion of the energy spectrum.

There are three types of SWAP science data: real-time; summary;
histogram. Real-time data, at rates up to 1Hz, provide the most
detailed science measurements since they contain the full count
rate distribution as a function of energy (speed). For science
summary and science histogram modes, the full distribution is not
recorded. Instead, parameters are derived from the count rate
distribution stored by SWAP. These derived parameters require less
memory than storing the whole distribution. The science summary
and science histogram modes are primarily used during the cruise
phase of the mission. For science data, the common data product is
usually a binary table; for calibrated real-time data,
spectrograms as images are also provided. Typically the tables
have instrument parameters and measurements in the columns and
measurement times in the rows, but the actual format depends on
the type of data and the processing level (raw vs. calibrated).
Other tables containing housekeeping and other parameters are also
provided.

Labels were redesigned during migration using the .FIT header and PDS3 .LBL
files, but the data files are unchanged from their PDS3 version.
