Hi Holly,

All things SVT have been kicked into high gear, so all the fun we were having coding together and looking at ECal data has ground to a halt.  However, I can probably get with Jeremy long enough to agree on a solution that he can code up when he has time. We should really have alignment constants that go into the conditions database for this, like we do for the SVT, since it's possible that these constants could change before/after an access.  Just putting in the important constants (six each for top and bottom to describe translation and rotation relative to ideal) shouldn't take too long.  I'll try to get with Jeremy quickly before the end of the day and report back what we think we should do.

Best,
Tim

So, we never thought of the code as serving for a real detector which we assumed might end up looking very different. As a result, the parameters defining the geometry are as minimal as possible and we didn't build in all of the flexibility that one would want for a real detector.  So... at the moment I think one can only define a separation between the top and the bottom.  However, it wouldn't be hard to change to having a separate value for the vertical position of the top and the bottom halves.  Jeremy and I can probably look at this in the next few days when we sit down to work on some analysis of the cosmic data we have been playing with.
