<p>The SPEDAS development team is pleased to announce the release of SPEDAS 4.0! </p>
<p>SPEDAS 4.0 includes numerous updates and enhancements to the
command-line TPLOT plotting and analysis tools, as well as the GUI
plotting and analysis tools. New plugins have been added to load MICA
induction magnetometer data, and Cluster datasets available via SPDF.
Several other plugins were updated with the latest available tools from
their respective development teams. In particular, the MMS plugin has
been updated to fix a bug that caused problems when using SPEDAS 3.2 to
download data from the MMS Science Data Center.</p>
<p>The latest IGRF-13 field model has been added to SPEDAS 4.0, and is
now used for coordinate transforms to and from the GSM system.</p>
<p>SPEDAS 4.0 includes support for downloading data from servers using
the DAS2 protocol. Several crib sheets are available showing how to
download data for the Galileo, Cassini, and Juno missions. This feature
requires installation of an external DLM and platform-specific shared
library (much like the GEOPACK and SPICE libraries), and is currently
available for Linux and Windows only. Many thanks to Alexander Drozdov
at UCLA, and Chris Piker at University of Iowa, for making DAS2 services
available in SPEDAS!</p>
<p>For a more detailed list of new features, enhancements, and bug fixes since SPEDAS 3.2, please see the release notes, at <a href="http://spedas.org/downloads/SPEDAS_4_0_release_notes.pdf">http://spedas.org/downloads/SPEDAS_4_0_release_notes.pdf</a></p>
<p>As usual, SPEDAS 4.0 is available as a source code zip file (suitable
for users with full IDL licenses). For users without IDL licenses,
we have also released the SPEDAS 4.0 “virtual machine” executables for
Linux, Mac, and Windows. SPEDAS 4.0 downloads, installation
instructions, and platform-specific installation notes are available via
the <a href="http://spedas.org/wiki/index.php?title=Downloads_and_Installation">SPEDAS wiki Downloads and Installation page</a> .</p>
<p>Please email questions, bug reports, help requests, and enhancement suggestions to <a href="mailto:SPEDAS_Science_Support@ssl.berkeley.edu" rel="noreferrer noopener" target="_blank">SPEDAS_Science_Support@ssl.berkeley.edu</a></p>
<p>
The SPEDAS software development has been supported by NASA contracts
NAS5-02099 (THEMIS mission), NNG17PZ01C (SPEDAS general development),
and NNG04EB99C (MMS sub-contract). We would also like to thank the many
software developers and SPEDAS users who have supported the development
effort by contributing code, reporting problems, and suggesting
enhancements.
