Tagger Momentum resolution
The tagger energy linearity plot has a slop of 1.004 +- 0.005
The multiple scattering plot fit gives: x/x0 = 2.94 +- 0.03
The (rescaled) momentum resolution fit gives a constant value: c = (1.395 +- 0.007)%
The momentum resolution, at different bending power, can be evalueted with:
dp/p(%) = c*BL_max/BL = 1.395*0.7089/BL
Calibration of the bending magnet
The bending magnet data have been fitted with a quadratic polinomial:
B*L (T*m) = 0.0012271*I(A) - 7.60132e-08*I^2(A^2)
