For Sherpa users, we have implemented a S-Lang version of the ACISABS xspec
model. A thread describing how to use the model is available at either of:
http://cxc.harvard.edu/ciao/threads/sherpa_acisabs/
http://ledas-cxc.star.le.ac.uk/ciao/threads/sherpa_acisabs/
Any queries about the S-Lang implementation should be directed to the CXC
helpdesk (http://cxc.harvard.edu/helpdesk/).
