keyword=Empty histograms due to Bad PedestalsThe empty histograms were caused by bad pedestals after the last
pedestal run. Unfortuantely I did not restore the good pedestals before runs 1520 and 1521 were taken. For 1522, everything is back to
normal.
Please be careful when taking a pedestal run on the L-HRS. I have
found that the software sometimes returns unreliable values, which
I haven't had the time to track down.
