; Two of many possible methods to output the status of the door open switch
; - assumes 5 minute data:
; Method #1: If the door is open even one reading during the output interval, output a 1
; for the Door variable
; Method #2: Door open status may be recorded as a fraction of the output interval
; (between 0 and 1) using the Histogram instruction.
