Total latency of the automatic processes during the S6/VSR3 run. The x-axis is the difference between the time at which the trigger was available for human monitoring and the trigger’s time. This includes an average of 63 s for all the data to be available at the Virgo site computing center and an average of 142 s for the trigger to be submitted to GraCEDb. This does not include the time for the human monitoring (~20–40 min) that takes place before an event is sent out for electromagnetic followup.
