Hi Peter,
  Thanks for wishing for a quiet night.  We all appreciate those types of
shifts.  In any case, I am quite hopeful that our optimizations this
evening will improve the data collection rate.  I think we have increased
the effective rate by 25-50% with the electron pileup removal and no more
interruptions of the beam.

Best regards,

Brendan
