END_OBJECT = TEXT END Volume JNOJED_2002 Juno JEDI Uncalibrated (EDR) Jupiter Data ============================================================================== Brief Volume Description ============================================================================== This volume contains 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 CATALOG/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 files are stored in the 'DATA' branch of the directory tree. The data are organized into subdirectories by year and day of year. The data on this volume are ASCII tables. The data files are named according to the convention: JED_AAA_TYPENAME_(E|C)DR_YYYYDDD_VNN.TAB where: AAA is 090, 180, or 270 depending on the specific JEDI sensor TYPENAME is a character string indicating the type of data (a list is provided in the JEDI SIS, Table 23, p. 55. TYPENAME is followed by EDR or CDR depending on the data level YYYYDDD is the year and day of year as described above NN is the version number of the file (starting with 01) The file extension for the data files is '.TAB'. Users of these data are encouraged to acknowledge both the PDS and the principal investigators of the instruments whose data are used in analysis in all publications. Please use the CITATION_DESC found in the file CATALOG/JEDI_J_EDR_DS.CAT for citing this data set. ============================================================================== Volume Set Information ============================================================================== This volume is part of the Juno JEDI volume set. This volume set includes the following volumes: Volume ID Description -------------------------------------------------------- JNOJED_2001 Juno JEDI Uncalibrated (EDR) Cruise data JNOJED_2002 Juno JEDI Uncalibrated (EDR) Jupiter data JNOJED_3001 Juno JEDI Calibrated (CDR) Cruise data JNOJED_3002 Juno JEDI Calibrated (CDR) Jupiter data ============================================================================== Mission Facts ============================================================================== The 'Juno Mission Phases' table below provides a list of mission phases for the Juno mission. It includes the phase start date and phase name. Descriptions of each of these mission phases are provided in the file: CATALOG/MISSION.CAT. ------------------------------------------------------------------------------ Juno Mission Phases ------------------------------------------------------------------------------ Start Mission Date Phase ============================================================================== 2011-08-05 Launch 2011-08-08 Inner Cruise 1 2011-10-10 Inner Cruise 2 2013-05-28 Inner Cruise 3 2013-11-05 Quiet Cruise 2016-01-05 Jupiter Approach 2016-07-01 Jupiter Orbital Insertion 2016-07-05 Prime Mission 2021-07-03 Extended Mission ============================================================================== File Formats ============================================================================== The data files on this volume are files are ASCII tables. The data files have detached PDS labels. The PDS label is an ASCII file containing information describing spacecraft, target, and observation parameters characterizing the associated data file. A data set description, instrument description, and other PDS documents are in .CAT files in the /CATALOG directory. In more recent versions of the Microsoft Windows operating system the .CAT by default is reserved as 'Security Catalog.' The .CAT files contained in this volume are ASCII text files, and can be read by any form of text editor. To make Windows open files with this name extension as text files right click the .CAT file, select with and choose a text editor to open the file. Additional documentation is located in the DOCUMENT directory. ============================================================================== Errata ============================================================================== Every effort has been made to assure that the data and documentation are of the best possible quality. However, mistakes are inevitable. There is a file called ERRATA.TXT found at the root level of this volume which contains a list of known deficiencies or caveats associated with data on this volume at the time this volume was produced. ============================================================================== Volume Contents and Structure ============================================================================== This section describes the volume structure and naming conventions.
