ID device:Back to main plotsNumber of doublets (two cosmic ray detections in an interval of 5 minutes) found in data (red) in every 24 hour period versus the expected value obtained from background simulations(dark blue). Number of doublets needed to obtain a 3 or 5 sigma effect are also given (green and light blue, respectively). Significance of number of doublets (two cosmic ray detections in an interval of 5 minutes) found in data in every 24 hour period. The number of detections per 24 hours (rate) as a function of time. Description of columns in the table: 2s observed  Number of doublets (two cosmic ray detections in an interval of 5 minutes) found in data; 2s expected  The expected value of the number of doublets obtained from background simulations; 3sigma  Number of doublets needed to obtain a 3 sigma effect; 5sigma  Number of doublets needed to obtain a 5 sigma effect.
