Bug List for Sherpa Beta

For an overview of known limitations in Sherpa Beta, refer to the About the Sherpa Beta Release webpage.

Caveat: Python Packaged with CIAO OTS

CIAO 4.0 uses the Python software packaged in the CIAO OTS directory for the Sherpa and ChIPS applications. In the window where CIAO is sourced any other Python installation is overwritten: this may interfere with other Python applications on the user's system. At present, the workaround is to run CIAO in a separate window from other Python applications. The CXC is working to resolve this issue.

Caveat: IPython Packaged with CIAO OTS

CIAO 4.0 includes IPython 0.8 in the CIAO OTS directory which is used by Sherpa and ChIPS to provide command-line user interfaces. These programs create an IPython profile in the directory $HOME/.ipython-ciao.

If IPython users want any personal customizations to be available when running CIAO, they will have to copy them from $HOME/.ipython to $HOME/.ipython-ciao.

Bugs

Sherpa hangs at startup (FC 7)

There is a blank line at the beginning of the $ASCDS_INSTALL/ciao-4.0/binexe/sherpa_py file. A user reported that this line caused Sherpa to hang when he tried to run the application on Fedora Core 7. The workaround is to remove the blank line from the file.
