Jan 2000 Official plots of 1kt momentum and profile (temporary)
Last updated 2000-Jan-23 by Y.Itow
Beam profile at 1kt
fiducial: sqrt( x**2 + z**2 )< 3.0 m && abs(y) < 3.0 m (vertical cylinder)
total photoelectron: 2000 < qismsk < 160000
Use single interaction: npeakspill==1&&ifgodspill==1
Target mass correction was done.
No efficiency correction due to photoelectron cut
normalization done by contents.
Crosses shows data, lines shows results of gaussian fit of data. MC is not ready.

Center of profile in 1kt coordinate (by gaussian fit)
Expected beam center is (H=0cm, V=-18cm)
Jun
horizontal : +20 +- 6cm
vertical : -31 +- 6cm
Nov
horizontal : +9 +- 5cm
vertical : -7 +- 4cm
Momentum and so-on at 1kt
fiducial: sqrt( x**2 + y**2 )< 2.0 m && abs(z) < 2.0 m (cylinder along beam)
total photoelectron: 2000 < qismsk < 160000
Use single interaction: npeakspill==1&&ifgodspill==1
No efficiency correction due to various cut
Fully contained (FC) cut is pomax < 200
Crosses shows data, MC is with Neut ver4.0 for jun and nov (blanc box) and ver2.4 for jun (hatched box).
Normalizaion of MC was done by number of FC events in FV.
