Glast System Tests plugin for JAS3

Installation

1. Make sure you have Java 1.4 installed (you probably have it for vrvs). If not install from: http://www.java.com/
2. Download and install JAS3 0.7.6 from http://jas.freehep.org/jas3/download.html
3. Start JAS3, from the menu select View, Plugin Manager. Click on the "Available" tab (if it shows no plugins available close the plugin manager, wait a few seconds, and then try again. It needs to download the list of plugins from SLAC and sometimes it takes a few seconds).
4. In the tree select astro->glast->Glast System Tests
5. Select Install selected plugins.
6. If new versions of the plugin become available you will be informed when you start JAS3, and can choose to install the new version automatically.

Running

1. From the JAS3 menu select File, Open Data Source. Select Glast System Tests and click Finish
2. Use the toolbar to select which versions you want to compare.
3. Drill down in the tree to select plot of interest. Double click to view plot.
4. Select a folder, such as MC Stuff, right click to bring up popup menu, choose "Show All" to show all plots in that folder
5. To close the glast system tests bring up the popup menu on the "Glast System Tests" node and choose close.

Current Limitations/Bugs

1. Data is read from rootd at SLAC, so network connection is needed to view data. In future it should also be possible to download data, or use data already cached on disk ("offline mode").
2. When connecting to root daemon a "progress box" is shown. Currently the progress box always goes away after 10 seconds, but the connection may actually take longer over a slow connection (it continues to connect even though the progress box is gone).
3. There is some problem with the root daemon on glast03, where sometime it refuses to accept additional connections resulting in a "timeout" message. I am investigating this.
4. Currently only "MC Stuff" plots are shown (others just need to be added to XML file)
5. We should support dragging plots onto different regions of the page, and selecting arbitrary sets of plots to display on a page (this is supported in other JAS3 plugins and should be easy to add).
6. When the versions are changed, currently displayed plots should update.
7. Plots with bad KS comparisons should be highlighted in the tree.
8. There should be an entry in the preferences dialog which allows opening the glast systems test on startup, and allows the XML file to be read from an alternative location, allows display preferences to be set, etc.
