QSAS: Science Analysis Software for Space Plasmas
QSAS current version is 3.2.0
Both Windows and Macintosh versions are complete and self contained. It is no longer necessary to install QT5 or CDF.
This is a major release with time handling completely revised.
Times are now stored in TAI (with leap seconds) to nanosecond accuracy, and conversion to
ISO UTC time strings is performed on the fly as needed.
Times appear as UTC strings in all widgets and on plots, which can also handle leap seconds.
Save restore has also been modified to improve speed, and version 3.1.7 has been released in parallel with 3.2.0.
QSAS version 3.2.0
QSAS version 3.1.7
Currently available for Linux, Mac OSX and
Other specifications can be found within the various items supplied with QSAS.
Please email CSC Support each time you download a qsas distribution, stating which version, so that we can keep users informed of changes and monitor levels of interest. QSAS is provided free under GPL public licence, see licence file.
should download the source distribution which builds itself using a
build script (QSAS_3_1/bin/build). Edit the script to give the location of the QSAS
distribution after download and the target directory for installing QSAS
into, along with QT, and CDF installations on your platform, then type
'./build qsas' in the bin directory of the distribution:
Mac OSX users should download the disk image.
Extract and drag
the folder QSAS_3_2 to /Applications.
The first time a new QSAS version is run
it may be necessary to open System Preferences -> Security &
and select 'anywhere' from 'Allow apps downloaded from'. Once QSAS has been launched for the first time this may be restored to your own preferred security settings.
This also contains the full src tree and can be built from the script bin/build in the case of local difficulties.
Launch QSAS on the Mac by double clicking on the QSAS icon /Applications/QSAS_3_2/QSAS.Contact CSC Support for earlier versions of the operating system.
Windows users should download the following archive:

Plug-ins written by the QSAS team are distributed
with the QSAS tar files, and install automatically at QSAS installation.
Many of the plugins provided by Stein Haaland are also distributed with QSAS precompiled.
Other QSAS plug-ins are also available from Stein Haaland.
QSAS is built around the prototyping methodology, and continual improvement and enhancement is central to its development. Some enhancements will come via user-written modules which are incorporated via the QSAS plugin interface. The development team welcomes comments, reports of anomolous behaviour, and suggestions which should be sent to: email@example.com.
When submitting a report, please
try to be as complete and specific as possible. If reporting a bug it can prove
useful if you are able to identify a reproducable sequence of events and a
specific data set. The save and restore session facility in qsas 2 can assist
in providing feedback since save session directories can be tarred and emailed
(save files are platform, independent). The environment variable QSAS_DEBUG can
be set "ON" in the user's QSAS script. This prints progress information
to the terminal. Sending us the last few hundred lines of this output can also
assist in diagnosing problems.
· The binary executables shipped with qsas have the debug symbols stripped from them before distribution. If you wish to run qsas with a debugger, for example when debugging a user written plug-in, then these symbols should not be stripped from a locally built source copy (use "make install" rather than "make install-strip").
The preferred wording for acknowledging use of QSAS in publications is "Data analysis was done with the QSAS science analysis system provided by the United Kingdom Cluster Science Centre (Imperial College London and Queen Mary, University of London) supported by The Science and Technology Facilities Council (STFC)" or similar wording as appropriate.
