Hello everybody,

Here is some latest TOF "events":

February 7th :

-HV was updated on whole TOF but Sector-1 Pannel-1. It was a try to get
new cosmic data but it failed. DIMAN didn't work properly and SC Dicriminators
were at 8 mV threshould.

In case of having some time for laser runs on Mon. I can quickly restore December
HV setup. But it doesn't look like we'll have that time.

February 8th :

-Pedestals have changed. Probably it was the overhit problem. New Pedestal
run was taken with hot counters OFF (sec2-2R, sec4-33R), SPAR file and
ONLINE MAP were updated : clas_fc_peds_008531.A00
It seems that the reasonable offset for the hot couters is about 100 ch.

-Cosmic rays run with the EC in trigger was taken: run #8532 (no data file, only
histogram file with pixel cut and a monitor file).
New trouble list and new upgrade of HV is gonna appear on Mon.

Costy.
