Iris 1.2 Release Notes

Version 1.2 summary list

o Visualization and SED browsing improvements

o Stable Software Development Kit for Plugins

o Improvements to the Sherpa SAMP connection management

o Many Bug Fixes

SED visualization and browsing improvements:

• Segment browser
• Metadata filtering by Boolean expression
• Individual point metadata popup restored
• Data point coloring
• Plot has legend explaining difference between points with error and without
• The Visualizer picks as default display units whatever units are present in the last segment added by the Builder to the SED

Sherpa SAMP

If there is no SAMP hub to connect to, sherpa_samp waits and periodically checks to see if the SAMP hub is now active. When the hub becomes active, sherpa_samp connects and registers the Sherpa process.

sherpa_samp has signal handlers for the SIGINT and SIGTERM signals. If it intercepts the SIGTERM signal sherpa_samp disconnects from the hub and exits with a nonzero status. If it intercepts a SIGINT signal, it disconnects from the hub and raises a KeyboardInterrupt exception in Python.

Iris Framework

• Sherpa is launched and killed by the launching script, not by Specview.
• The launching script sends a SIGINT signal to sherpa, so that it can shut down cleanly.
• The Plugin Framework has been completely redesigned and it should be now ready for production. In particular, the new framework allows to install and uninstall plugins "on the fly", and supports custom icons.
• The new Plugin Manager is the GUI for installing and uninstalling additional plugins. You can both install and uninstall them at runtime... no need to restart Iris. The additional buttons and menus will come and go.
• An example Plugin is included in the examples directory, to exercise the Plugin Manager.
• New SDK available for developers of third party plugins. The SDK has the form of a Maven archetype that can be used to generate stubs of plugin projects and already configured to build compliant plugins. The iris-common library can be used by developers not willing to use Maven and directly managing their external dependencies (this is possible but not recommended).
• Added ASDC plugin (1.1.3) to contrib directory.

Bug Fixes

• BR-106: move left button doesn't work.
• BR-110: displays error dialog if Sherpa not connected to SAMP hub.
• BR-116: input points in magnitude units do not display error bars.
• BR-117 SED Builder fails to show error message when an incompatible spectrum/SED is added
• BR-122 Iris script does not reset PYTHONPATH variable
• BR-125 Missing Iris data files
• BR-126 Tool tip text on IRIS display window too techy
• BR-128 Exception message when starting IRIS on Mac 10.7.4 with Java 1.6.0_35
• BR-131 Trouble loading FITS format files
