These X-ray pulses take 300 years to traverse the distance between the central black hole and a large cloud known as Sagittarius B2, so the cloud responds to events that occurred 300 years earlier.

Its value according to the binary number displayed on the P1 mouth drive leds. 2, external event count pulse introduced by P3.4 T0 timer.

The time analysis signatures include the number of time m pulses occurs in a time interval, that is triggered randomly, upon a detection event, or upon a source fission event triggered.
