Hi,

I attached two plots showing the differences of the TDC offsets in
blast.sc_cal of before the TDC modules were moved versus after (in
channels, 20 channels = 1 ns).

A positive number means that the offset has become bigger.

blast.sc_cal v16 is from last Saturday, I generated it based on cosmics
run 7150 (from May 5, 2004)

blast.sc_cal v17 has been introduced with run 8817 (July 12, 2004). I
generated it based on flasher monitoring, evaluated for run 8650.

Not all of the changes might be due to the swapping of the modules (which
happened before run 8635, some part of the oserved change may also be due
to drifts of the offsets in the period from run 7150 to 8635.

Regards,

Michael
