Study of no SL3 method of XFT Data Size Reduction

Plot of Z0 resolution (picking a random track between the fiducially viable ones)


Here the resolution is bad, compared with 11 cm. These are good quality muons at low luminosity (80-90*10E30)

Plot of cotan resolution


To be compared with 0.12 for the nominal algorithim.

Degeneracy of choices for SL5 and SL7 (# clusters @ SL5) * (# clusters @ SL7)



For comparison, the multiplicity of delta357 in the other data. This would be "number of tacks we make with delta357==0" for every event. Not exactly the same thing
