Systematic error for event rate and number of SK expected
events. There is an addditional error due to FADC problem only in Nov.99 data and
it is added linearly.

Summary of event rate and SK expected events.

Event rate stability. Horizontal axis : integrate CT from
Nov., Vertical axis : nu interaction /E12 p.o.t . Additional error due to FADC
problem is added to Nov. data

Profile
Volume for profile is a cylinder along to the tank axis.
Each bin is normalized by volume.
Mean value (gaussian fit) of X profile is +20.8+-2.3 cm (stat).
Mean value (gaussian fit) of Y profile is -11.8+-1.9 cm (stat).
FADC peak time distribution
Time distribution of all / first FADC peaks.
You can see 9 bunches of the beam structure.
