Fields:

      Attribute(s):  

      Brief:  "GEM low-rate science dead zoned counter"

      Instance(s):  dead

      The GEM maintains a counter of the number of times that a window failed to open because one or more enabled conditions occurred within the dead zone. If a condition occurs within the dead-zone, but is not enabled, the counter will not increment. If more then one enabled condition occurs simultaneously within the dead-zone, the counter increments by only one.

      Attribute(s):  

      Brief:  "GEM low-rate science discarded counter"

      Instance(s):  disc

      Window turns discarded due to busy

      Attribute(s):  

      Brief:  "GEM low-rate science livetime counter"

      Instance(s):  live

      1/deadtime statistics

      Attribute(s):  

      Brief:  "GEM low-rate science sent counter"

      Instance(s):  sent

      Window turns which result in a sent message

      Attribute(s):  

      Brief:  "Low-rate science prescaled counter"

      Instance(s):  presc

      Window turns discarded due to prescaling
