Abstract
========
This data set consists of the JUNO JEDI (Jupiter Energetic-Particle
Detector) uncalibrated observations, also known as EDRs. The system
is made up of 3 instrument subsystems (pucks) aligned in three
directions on the spinning JUNO spacecraft. The pucks each have 6 look
directions (telescopes) with a time of flight (TOF) and a deposited
energy detection (SSD) system. In addition, the pulse height of the
signal in the TOF system can be used for energy measurement. The
instruments can be operated in a variety of modes, differing in the
way they use and combine these measurements. More details are available
in the INSTRUMENT.CAT file and the JEDI SIS.
The EDRs are organized in files covering one day of spacecraft event
time (SCET). There are potentially 10 different files per puck,
corresponding to the available data gathering modes: HIERSESP,
HIERSISP, HIERSTOFXER, HIERSTOFXPHR, LOERSESP, LOERSISP, LOERSTOFXER,
LOERSTOFXPHR, NONPTOFXER, NONPTOFXPHR. Depending on how the pucks are
operated, not all data types will be available for all pucks for any
particular time range."

Data Set Overview
=================
The data set consists of uncalibrated observations, also known as
EDRs.
For all the EDR products there is a detached PDS label file that
describes the contents of one data file. Each label file will have
the same base name as the data file it is describing, with the
extension .LBL to denote a label file. The label file defines the
start time and end of the observation, product creation time, and
the structure of the ASSCI tables. Each data product
is identified within the PDS label by a STANDARD_DATA_PRODUCT_ID
value, shown in parentheses in the table below.
Instrument Overview
===================
The JEDI sensors consists of a 60-mm diameter, hockey puck-like
cylinder, in which a start foil and stop foil, wrapped around
opposite curved sides of the cylinder, constitute the TOF chamber.
The detectors are arranged so that each detector senses the
events within a given range of incidence angles. Each of the 6
detector modules is composed of 4 pixels: large and small ion and
large and small electron. See the INSTRUMENT.CAT file for more
information.
Calibration Overview
====================
This data set is NOT calibrated; it only provides the uncalibrated
sensor measurements.
Parameters
==========
The setting and interaction of the actual instrument parameters
used to configure the timing and modes of the collection of spectral
data during normal science operations are complex and a detailed
understanding of them is not required outside of science operations
team. We present science parameters that describe the data collection
settings in a useable fashion:
UTC - a human readable timestamp provided for ease of use. The ET
timestamps are preferred for actual analysis.
ETStart, ETLookDirection, ETEnd - Time stamps in Solar System
Barycentric time (TDB, Epoch J2000) corresponding to the beginning,
middle (roughly), and end of the data accumulation. See JEDI SIS for
a detailed description of the ETLookDirection parameter, which is the
recommended SCET time to use for data analysis.
Duration - Total live exposure time
SectorDeadTime - instrument dead time due to latency in switching
between collection modes.
LargePixel - wether the large or small detector pixel is in use.
SCLKStart, SCLKLookDirection, SCLKEnd - spacecraft clock strings
corresponding to the same three times as the ET parameters.
Quality - a multi-bit flag indicating data quality issues. 0 means no
adverse conditions
PacketTimeTag, Spin, Sector - retained for instrument science team
usage in data validation
Data
====
The JUNO JEDI EDR data set products are described as follows:
HIERSESP High-Res (E) Electron Spectra
LOERSESP Low-Res (E) Electron Spectra
Electron spectra as measured by the solid state detector system (SSD)
The High-Res product has more energy channels but is collected at
a longer cadence than the Low-Res product.
HIERSISP High-Res (E) Ion Spectra
LOERSISP Low-Res (E) Ion Spectra
Ion spectra as measured by the solid state detector system (SSD)
The High-Res product has more energy channels but is collected at
a longer cadence than the Low-Res product.
HIERSTOFXER High-Res (E) Time Of Flight (TOF) x Energy Ion Rates
LOERSTOFXER Low-Res (E) TOF x Energy Ion Rates
NONPTOFXER Non-proton TOF x Energy Rates
Ion spectra as measured by the SSD and the TOF systems working in
concert. The High and Low Res products are defined as above and
contain data for energetic charged protons. The NONP data contain
data for other ion species.
HIERSTOFXPHR High-Res (E) TOF x Pulse Height Ion Rates
LOERSTOFXPHR Low-Res (E) TOF x Pulse Height Ion Rates
NONPTOFXPHR Non-proton TOF x Pulse Height Rates
Ion spectra as measured by the TOF system using the pulse height of
the TOF signal to measure energy (this allows us to measure lower
particle energies). The High and Low Res products are defined as
above and contain data for energetic charged protons. The NONP data
contain data for other ion species."

Confidence Level Overview
=========================
The JUNO JEDI EDR data are the least processed data set released for the
instrument. Data presented here are an accurate representation of the
JUNO JEDI data as received from the spacecraft, with minimal timing and
no spatial processing.
Review
======
The JUNO JEDI EDR were reviewed internally by the JEDI team prior to
release to the PDS. PDS also performed an external review of the
JEDI EDR.
Data Coverage and Quality
=========================
Limitations
===========
This data set is minimally processed data. The data are received
from JUNO mission operations center and processed by the JEDI instrument
team and delivered to the JUNO Science Operations Center (JSOC).
