Hi,

Pedestal calibrations for runs 9345-10500 are now completed for detectors:

BBL, BBR, ZDCL, ZDCR, TOF1, TOF2, TOFW, TFW2, RICH, TRMRS, TRFS

Run 10149 makes my scripts crash - I suspect it has something to do with
the date of the run in the db (19691231).

Observed problems (-1111 is in the db for these channels):

- Bbr tube 15 has pedestal width ~20 for runs 9391-9553.

- Tof1 B32 have a pedestal width of 30-40 channels. In few runs it's <10.
  Maybe we should put in -1111 for all runs.

- Tof2 slat 20 (top+bot) have wide pedestals for runs 9924-9939.
- Tof2 B2 has a very bad pedestal (2 wide peaks) except for a few runs
  around 9600. Maybe we should put in -1111 for all runs.

- Tofw slats 89 and 97 are bad.

- Tfw2 slat 8 (top+bot) is bad after run 9449
- Tfw2 B1 is bad (w=40) in run 9449 only. Maybe we should chack the data
  run after and see is it's also wide there.
- Tfw2 B2 is bad (w~40) from run 9507
- Tfw2 B28 and B41 are bad (w~40) up to run 9901

Cheers,

Claus
