Also one of the things I used to do with the unix environment was to set up a series of different autobak files with different rback settings so I could see the effect of moving the fit window. It was nice to be able to compare all of these in the same graphic window

For what it's worth --- this can be done in Athena fairly easily. 1. Read in your mu(E) data. 2. Using the Group menu, make several copies of that data group. 3. Set Rbkg as desired in each copy. 4. Mark all the copies. 5. Click the purple k or R buttons. It would be nice to have a way of probing individual parameters for single groups without explicitly making copies. If anyone pipes up in support of that idea, I'll throw it on the todo list.
