Hi Zisis,

    I have these running now. Several of them are already done and the
rest should show up over the next several hours in /work/halld/bcal06.

IMPORTANT: During the last batch of runs last week, I found a bug in the
tagger energy reconstruction. There was a bad index in the code that
looked for e-counter overlaps. This would have caused about a +/-0.1%
systematic shift in the energy reported by the tagger for as many as
two-thirds of the events. All of the files produced last week have the
fix now. There were a couple (3-4) that were produced early on that
exposed the bug. I have since re-run those so that they were all
produced with the same code. Let me know if you have any questions.

Regards,
-David
