Analysis (my suggestion) target vertex (theta,phi) as input parameters.
Can we neglect phi dependence for our purpose?
Plots below show beta and vertex information as derived from disc data only (example of ToP
readout here, little mirrors but no multiband).
Visualisation of Results
Without phi dependence the results can be shown in a singe plot.
- sigma lines as function of angle and momentum:
- tagplot2.eps: sigma lines as function of angle and momentum
with phi dependence, no B field
Taking phi dependence into account, one has three input parameters and hence has to create a series of plots. For a given momentum the theta-phi-plots might look like these below (disregard the numbers, they only relate to sigma values).
- Example plot without B:
with phi dependence, B field
With magnetic field the gemoetry will be distorted as a function of momentum. One sees that only near the rectangular cutout the rotational symmetry is affected.
