MUON CHAMBER / Fe event official plots
25/July/2000 after SK efficiency
corrected.
Last up-dated on 13/Oct./2000,
add profile figures.
Analysis details are described
here.
DATA summary, DATA/MC:
SK expect:
Event rate stability:
Normalized to Target-CT(CT16)=5e+12ppp.
-
[99June-00June]
-
[99Nov.-00June]
Averaged rate which is shown with dashed line, is 0.047event/5e+12ppp
for 99June, 0.054 event/5e+12ppp for 99Nov-00June.
Chisquare from the averaged rate is 63.1/d.o.f.40 for
99June, 175.3/d.o.f.240 for 99Nov-00June, respectively.
Neutrino profile:
Vertex profile after acceptance/detector
mass correction.
The designed beam center is x=0cm,
y=-15.8cm
The fitted center have +-20cm precission
as systematic error.
Muon energy spectrum & angle distribution:
DATA & MC are normalized with its
'sum'.
Error bars are statistical errors
only.
