Hi Tim, Jeremy,

I was wondering if you had been able to take a look at ecal geometry. It
would be nice to input the surveyed ecal geometry from the commissioning
run so that we can use this for our calibration studies. We would need to
just input a small rotation and translation on the top 1/2 of the ecal.
