I got some long counts from my telescope. With 0° zenith angle, 8 cm distance between tubes, counting for 3 hours and 17 minutes, I got 42 coincidences, that is 0.213 count/min. I also computed spurious coincidences due to the length of the GC pulses, that is 0.04 count/min. So I suppose that the real cosmic coincidence could be 0.17. |
