I have released the standalone version of Sherpa 4.4 at the Sherpa website:
As in past releases, the purpose is to allow Python users to install Sherpa as a Python module, without reference to any other CIAO package or program.
I release the source code tarball, sherpa-4.4.0.tar.gz, that contains all the Sherpa source code we released with CIAO 4.4. Release notes can be found at NOTES-4.4.0.txt.
As time permits, I will go on to add Mac disk images, and/or eggs for Linux, for binary installations of Sherpa. When these binaries are ready I shall post an update here.
