h1. GEM DB Variables

* *bb.gem.m#.position* - Position of the center of the module relative to the first module in the stack.

* *bb.gem.m#.angle* - Angle of the module.

* *bb.gem.m#.maxstrip_t0* - Mean time where good strips are expected. This is only applied to the maximum strip.

* *bb.gem.m#.maxstrip_tcut* - Cut around mean time (above) where good strip times are expected. i.e. good strips will have a time that is within t0 ± tcut. This is only applied to the maximum strip.

* *bb.gem.addstrip_tcut* - When forming clusters all strips in the cluster must have a time difference between them and the max strip that is less than this value.

* *bb.gem.addstrip_ccor cut* - ADC correlation between strips and the max strips in a cluster must be greater than this number.

* *bb.gem.m#.threshold_sample* - Maximum ADC time sample for a strip must be above this threshold.

* *bb.gem.m#.threshold_stripsum* - Strip time sample ADC sum must be above this threshold.

* *bb.gem.m#.threshold_clustersum* - ADC sum of all strip sums in a cluster must be above this threshold.

* *bb.gem.m#.ugain* - Gain of each APV card on the U axis of this module.

* *bb.gem.m#.vgain* - Gain of each APV card on the V axis of this module.

* *bb.frontconstraint_x0* - Calorimeter front constraint mean x position.

* *bb.frontconstraint_y0* - Calorimeter front constraint mean y position.

* *bb.backconstraint_x0* - Calorimeter back constraint mean x position.

* *bb.backconstraint_y0* - Calorimeter back constraint mean y position.

* *bb.frontconstraintwidth_x* - Calorimeter front constraint x width.

* *bb.frontconstraintwidth_y* - Calorimeter front constraint y width.

* *bb.backconstraintwidth_x* - Calorimeter back constraint x width.

* *bb.backconstraintwidth_x* - Calorimeter back constraint y width.
