QSAS: Science Analysis Software for Space Plasmas |
QSAS current version is 3.3.9
Both Windows and Macintosh versions are
complete and self contained. It is no longer necessary to
install QT5 or CDF. However, older versions of the operating
system may block the running of a newer binary. If you cannot
locate a version that works for your OS please contact QSAS Support .

QSAS version 3.3.0
QSAS version 3.2.6
- New Vector Plugins
- Div(tensor)
- Grad(vector)
- Sum down option added in PSD slice
- Plot, added toggle to use 'Object Info' as plot Legend text
- "Time Intervals" on Working List now called "Time_Intervals"
- helps batch scripts
- has backward compatibility for savesets
- Bug fixes, including:
- Problem in slice in 3D plot at phi near 45deg and theta near 90deg
- Find/Replace not updating plot object
- Legend when time axis runs backwards
- Minor fixes in batch processing and calculator
QSAS version 3.2.5
- Phase Space Density tool greatly improved
- Much more control over slices (and moved to a single interface)
- Polar and cartesian slices on linear or log scale
- Much faster slices and Pitch Angle Distribution with control over interpolation.
- Convert PSD to velocity space
- PSD values along a vector
- New capability in 3D plotting.
- Option to view slice normal to any axis or a user specified direction
- Interactive control of slice displacement and orientation allowing user to scan through the data using the sliders
- Ability save the vector to the slice centre from data origin onto the Working List. Thus by centring the slice on a feature its location may be determined and saved as a vector offset.
- Add:
- Shift-click in plot window saves selected time to Time List
- Bug fixes, including:
- Various bugs in plot page layout
- Fix symbols reversed or upside down when axes run backwards
- Fix Linear regression on log and log-log plots
- Fix various calculator bugs
- Fix missing signals in plot: page size options focusOut()
- Fix plot not updating default colours when object changed
- Fix metadata SI_conversion when multiplying
QSAS version 3.2.4
Internal release for testing only.
QSAS version 3.2.3
- QSAS now draws its own plot symbols instead of using plplot glyphs:
- Greatly improves accuracy of symbol placement
- Improves plot speed when symbols used
- Improves correspondence between screen, plot files and print versions of plots
- Note: Custom symbols and those below 'custom' on the menu still use plplot glyphs
- Fix bug in getting time average from plot
- Fix bug in plot not always updating cache when typing in a field
- Fix bug in calculator when extracting metadata
- Other minor bug fixes
QSAS version 3.2.2
- Fix crash in object editor if button pushed twice
- Fix gap handling in boxcar join
- Fix validation on rename or move items on Working List
- Added Find/Replace in data slots
- Added Undo in data slots
- Modified data slot validation to be more consistent
- Fix bug in PSD tools not correctly converting energy threshold from eV if single value provided
- Fix bug in calculator, restore not setting the output object names fully
- Fix crash in editing colour table (Hue range)
- Changes to metadata handling inside file reading modules
QSAS version 3.2.1
- Improved Linux compatibility
- Fix isRegular() to return seconds, not nanoseconds
- Fix timeline option not restoring properly in the calculator
- set error if opThis fails for all op
- Join Automatic option moved
- Separate DV_GAP_BOX_WIDTH and disable GAP value for boxcar
- When plotting multiple pages, window id lists now updated properly.
- Fix write epoch16
- Export/Join GUI feedback now properly updating on drop and item select
- Tetrahedron Plugin axis ratios now isotropic again
- Fixed plot time interval not always refreshed on load plot profile or in batch
- Plot to PDF and print, improve line widths and font sizes compared with screen plots
- Legend line lengths may now be zero (no line)
