Introduction
=============================================================================
The JNOWAVS1000 volume contains all available Waves instrument Survey science
data records from launch though the end of mission. Data provided on this
volume are at the highest available time and frequency resolution and have
been calibrated into physical units using the best calibration tables
available at the time of publication.
Every effort has been made to assure that the data and documentation are
of the best possible quality. However, mistakes are inevitable. The PPI Node
of the PDS will maintain an online list of ERRATA where errors and updates are
documented. Should any user of this product find an error on this volume,
please report the error to the PPI Node so that the finding can be made
public.
=============================================================================
Quick Start Summary
=============================================================================
This volume, JNOWAVS1000, contains Juno Waves records from the entire
mission, and will be updated as new data become available. This release,
Version 28, includes all available records for spacecraft event
time (SCET) dates 2011-08-05 up to, but not including, 2024-03-24T00:20:03.
Calibrated values have been written into the product files, thus there is no
need to transform values via software when reading the product files.
KEY THINGS TO KNOW IN USING DATA ON THIS DISK:
* A web browser can be used to view all the data in this archive in the
form of Portable Network Graphics (PNG) files which are image files of
frequency-time spectrograms by navigating to the BROWSE directory and
clicking on the image files provided. In most cases each pixel in the
image files corresponds to an average of many measurements, either in
frequency or in time. Thus the image files are a REDUCED RESOLUTION
data set.
* All data files are stored under the DATA top-level directory and are
organized by data set and spacecraft event time. The DATA directory
branches off into:
WAVES_SURVEY - relatively low resolution spectrum analyzer data
These data are available whenever the Waves instrument is operating
and provide an overview of the electric wave spectral densities from
50 Hz to 41 MHz and magnetic wave spectral densities from 50 Hz to 20
kHz.
* General information on all Waves data sets may be found in the volume
software interface document (VOLSIS) in DOCUMENT/VOLSIS/INDEX.HTM.
In addition information specific to this volume is provided in PDS catalog
files located in the CATALOG directory. The data sets are documented in:
* SURVEY_DS.CAT, describing WAVES_SURVEY products
Other PDS catalog files include:
* INSTHOST.CAT, describing the Juno spacecraft
* MISSION.CAT, describing the Juno mission
* PERSON.CAT, listing Waves instrument operation team members and PDS
personnel
* PROJREF.CAT, listing useful literature references for the Juno mission
* WAVESREF.CAT, listing useful literature references for the Waves
instrument
* WAVESINST.CAT, describing the Waves instrument
=============================================================================
Relationship to Other Data Sets
=============================================================================
Many plasma wave phenomena are easier to interpret in the presence of other
particles and fields measurements. In particular knowing the local DC
magnetic field is useful for determining key frequencies such as the electron
cyclotron frequency and the upper and lower hybrid resonances. Since the
Waves instrument does not directly measure DC fields these measurements must
be obtained from another source. The recommended source is volume(s)
JNOFGM_1000 from the Juno MAG instrument team. The Juno MAG volume should
be available from PDS/PPI node operator.
If an un-calibrated source of these data should ever be required, the raw
experiment data records (EDRs) used to generate the products on this volume
may be found in the Waves Raw Products volume JNOWAV_0000. If the "as-flown"
command sequences sent to the Waves instrument are ever needed these are also
provided on the JNOWAV_0000 volume.
=============================================================================
File Formats
=============================================================================
The SURVEY data are stored as ASCII text values in comma separated values
files (CSV) which may by directly into many database management systems or by
office productivity software. These files end in the file suffix '.CSV', and
are accompanying by detached PDS label files ending in the suffix '.LBL'.
The label files provide descriptions of each column of the CSV files as well
as general information such as the calibration tables used to produce the
product. The first 5 rows of each spreadsheet column provide a data header
which include useful information such as the frequency bin center point and
noise bandwidth for each channel.
All documents, PDS labels, HTML and CVS files are stream format files, with a
carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of
the record. This allows the files to be read by Android, iPhone, Linux,
MacOS, and Windows systems. Many users may see an unnecessary carriage return
character (^M) at the end of each line. MacOS and iPhone users may see an
unnecessary line feed character (^J) at the start of each line.
PDS labels are object-oriented. The object to which the label refers (e.g.,
FILE, TABLE, etc.) is denoted by a statement of the form:
^object = location
in which the caret character (^, also called a pointer in this context)
indicates that the object starts at the given location. For an object in the
same file as the label, the location is an integer representing the starting
record number or byte of the object (the first record/byte in the file is 1).
For an object located outside the label file, the location denotes the name of
the file containing the object, along with the starting record or byte number.
For example:
^INDEX_TABLE = ("INDEX.TAB", 2)
indicates that the INDEX_TABLE object begins at record 2 of the file
INDEX.TAB, in the same directory as the detached label file. Below is a list
of the possible formats that use the ^object keyword.
^object = n
^object = n<BYTES>
^object = ("filename.ext",n)
^object = ("filename.ext",n<BYTES>)
where
n -- is the starting record or byte number of the object,
counting from the beginning of the file (record 1,
byte 1); default is record number.
❮BYTES❯ -- indicates that number given is in units of bytes.
filename -- upper-case file name.
ext -- upper-case file extension.
=============================================================================
Software
=============================================================================
Since all data are stored as calibrated values, no end-user example code is
provided for reading data on this volume. The SURVEY files may be read by
many common programs.

Errata
=============================================================================
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. Any changes or errors that are
found on the JNOWAVS1000 volume set can be found on the PPI Node errata Web
