The AWARE database contains three types of housekeeping data.
Sensor Hk -- This includes all the environmental data on the status of the station, such as temperatures, voltages and currents.
Event Hk -- This includes all the data related to the performance of the trigger, such as thresholds and L1,L2,L3, etc. scaler rates counting the number of triggers at each point.
Header -- This data is derived from the actually events and so includes things such as event rate and channel RMS.
