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)%
Notice that some of the runs have a different magnet current (this is necessary if we don't change the geometry), but, after rescaling the resolution so a rescaling to the same bending power we observeis needed.
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:
