bb.gem.m*.position - Position of the center of the module relative to the first module in the
14
stack.
15
• bb.gem.m*.angle - Angle of the module.
16
• bb.gem.m*.maxstrip t0 - Mean time where good strips are expected. This is only applied to the
17
maximum strip.
18
• bb.gem.m*.maxstrip tcut - Cut around mean time (above) where good strip times are expected.
19
i.e. good strips will have a time that is within t0 ± tcut. This is only applied to the maximum strip.
20
• bb.gem.addstrip tcut - When forming clusters all strips in the cluster must have a time difference
21
between them and the max strip that is less than this value.
22
• bb.gem.addstrip ccor cut - ADC correlation between strips and the max strips in a cluster must
23
be greater than this number.
24
• bb.gem.m*.threshold sample - Maximum ADC time sample for a strip must be above this
25
threshold.
26
• bb.gem.m*.threshold stripsum - Strip time sample ADC sum must be above this threshold.
27
• bb.gem.m*.threshold clustersum - ADC sum of all strip sums in a cluster must be above this
28
threshold.
29
• bb.gem.m*.ugain - Gain of each APV card on the U axis of this module.
30
• bb.gem.m*.vgain - Gain of each APV card on the V axis of this module.
31
• bb.frontconstraint x0 - Calorimeter front constraint mean x position.
32
• bb.frontconstraint y0 - Calorimeter front constraint mean y position.
33
• bb.backconstraint x0 - Calorimeter back constraint mean x position.
34
• bb.backconstraint y0 - Calorimeter back constraint mean y position.
35
• bb.frontconstraintwidth x - Calorimeter front constraint x width.
36
• bb.frontconstraintwidth y - Calorimeter front constraint y width.
37
• bb.backconstraintwidth x - Calorimeter back constraint x width.
38
• bb.backconstraintwidth x - Calorimeter back constraint y width.
