Since the Feb. 26 meeting, I made a few modifications to my analysis:
upto 6 scintillator clusters are now allowed (instead of 4), adc overflow
cut was removed and a bug in applying the standard geometry cut was fixed.
I now see 187 events in the upgoing region. All these events (actually,
all 287 events before applying the standard geometry cut) were visually
scanned. 5 events of these 187 were deemed to be "fake" and were rejected.
(4 had an upgoing as well as a good downgoing track, and one was a showering
event). The 182 good events are listed below.
The background in the region -0.75 < 1/beta <= 0. was also visually scanned.
The events were mostly showering, with multiple tracks/box hits or with
a box from the North/South face. The number of events in the symmetrically
opposite region in 1/beta (2.75 <= 1/beta <= 3.25) is 2. I fit the upgoing
muon distribution in the region -2 <= 1/beta <= 0 to a gaussian plus linear
function. The background estimated by integrating the linear term of the
fit in the upgoing region is 2 events.

========================================================
Box1, Box2 numbered according to calmod, Trk = 1,2,3 for wire-strip,
wire-lateral, strip-lateral track. They define the best matching track-box
pair for the event. Plen is the path length of the track between these boxes.
