Hi,

after a closer examination of the PID in the AuAu and CuCu 62GeV I've
found the following for the MRS pid:

CuCu_at_62: Run 13654 - 13924
TOFW: Needs new topTdcOffset, botTdcOffset, deltaDelay, timeOffset,
effSpeedOfLight, topSlewPar1, topSlewPar2, botSlewPar1, botSlewPar2.
The entire set of data only has slat 33-60 with reconstructed hits. 

Top and Bot TDC offsets are the ones with the most -1111 commited
values...
and the slewing commited is -1111 for/from run 13608... 

TFW2: Needs new pedestals! there are 5-6 dead slats in more than half of
the run because -1111 was commited as the pedestal value (should only be
2 dead slats out of the 41). Then I guess the rest of calibs needs to be
redone after that...

I'll redo the TFW2 pedestal calibration!

AuAu_at_62:
TOFW: Looks good. (Though its strange that slat 30, 31 and 32 does not
work since they work in run6 pp_at_62...)

TFW2: 45 deg A and B looks strange, see attached plot of hits that have
an assosiated track. All calibs seem to in good shape. It seems this
track projection to TFW2 is really bad for all settings, see attached
plot. This could be due to something in the making of the DSTs. I'll
look into the dst macro...

pp_at_62:
Nice data set :-)

Cheers,
	Truls
