D1 Motors

Detlef Smilgies, CHESS

D1 is a complex beamline with about 40+ motors and just as many pseudomotors. Hence it seems useful to organize motors in groups. Each groups has specific "where"macros (provided after ">") to track the particular beamline component. The first two columns provide physical motors, the second two columns the derived macromotors of combined motions.

Explanation of the D1 motor naming scheme and a copy of the full spec configuration can be found here.
