Abstract
========
This data set consists of the JUNO JEDI (Jupiter Energetic-Particle
Detector) calibrated observations, also known as CDRs. 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 CDRs 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.
All the measured quantities present in the uncalibrated data files
(EDRs) are present here in three forms: counts per accumulation (the
same numbers as in the EDRs), counts per second (this number may be
corrected for instrument saturation and background), intensity (counts
per second per steradian per cm2 per keV). Additional support
quantities are also included for the convenience or enlightenment of
the end user.

Data Set Overview
=================
The data set consists of calibrated observations, also known as
CDRs.
For all the CDR 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 calibrated; it provides the instrument team's
best available interpretation of the measured data at the time
of release. This understanding is evolving and it is expected
that the calibration process will change and improve with subsequent
releases.
Parameters
==========
The timing parameters in the CDRs are identical to those in the EDRs.
See JEDI_J_EDR_DS.CAT file for a short description or the JEDI SIS for
more detailed information.
In addition to the timing parameters and the uncalibrated counts, and
calibrated counts per second and intensity spectra, for each data
record in the CDR, we include ephemeris attitude and pitch angle
information for the convenience of the end user. We also include a
subset of the basic rate information so the end user can obtain an
understanding of the level of activity in the instrument system as this
will affect the instrument performance.
The additional quantities are, in brief:
❮Ephemeris, Attitude, and Pitch Block❯:
Spacecraft Position - X, Y, and Z in the POS frame (POS = JSE for
observations at Jupiter).
Planetary Position - Latitude and Longitude in the LOC frame (LOC=
IAU_JUPITER for observations at Jupiter).
Look Direction - Unit Vector X, Y, and Z of the 'look direction'
of the negative of the incident particle velocity
vector for each telescope.
Pitch Angle (1 column per telescope = 6 columns) - The angle between
the incident particle velocity vector and the
local magnetic field.
❮Basic Rate Block❯ which of these values are present depends on the
data type, see JEDI SIS for details:
SSD0-SSD5 - Number of pulses on the Solid State Energy
detector for telescope number 0-5
VEP (Valid Events Processed) - Number of events actually processed by
the flight software
VEE (Valid Energy Events) - Total number of events in all SSD (Energy)
detectors.
Start0, Stop0 - Number of pulses on the end of the Start or Stop
anode nearest to look direction 0.
VTOFXE - Number of valid TOFxE events counted.
VTOFXPH - Number of valid TOFxPH events counted.
Data
====
The JUNO JEDI CDR data set products are the same as described in
JEDI_J_EDR_DS.CAT. "
CONFIDENCE_LEVEL_NOTE = "
Confidence Level Overview
=========================
The JUNO JEDI CDR data are, at the present time, calibrated simply by
multiplying by a factor, determined for each individual telescope and
pixel, which captures the efficiency and geometric factor for that
detector. The underlying counts per second rate has not been adjusted
for background or instrument saturation effects. These are strictly
preliminary calibrations at this time.
Review
======
The JUNO JEDI CDR 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
=========================
Data reported are the calibrated data for the time period:
2013-279T00:00:00 through 2014-104T23:59:59
Limitations
===========
The calibrations applied to the data both in terms of efficiency factors
and energy descrimination are still preliminary. Instrument team
calibration efforts are ongoing. "
