Subject:	CATS tracking efficiency

We noticed that the tracking efficiency was only 70% while the timing efficiencies were around 95%.
By lowering the thresholds (see Attachment 5-8) 89% tracking efficiency was achieved.
Note: analyzed run 293 (CATS1 640V, CATS2 670V), first 10000 events, only CATS trigger was selected.
