Checks for 5, 4 or 3 Sigma Significance



In addition to looking for an occurence of 7 events in the 100 second search or 5 events in the 1 second search, we will also check for the following, any of which have a statistical significance greater than 5 sigma:
-An occurence of 6 events and an independent occurence of at least 5 evenets in the 100 second search
-Three indepedent occurences of at least 5 events in the 100 second search
-Two independent occurences of 4 events in the 1 second search
-Two independent occurences of at least 5 events in the 100 second search and one occurence of 4 events in the 1 second search
There is a 1.2X 10-7 probability that one of these multiple event cases will occur due to random fluctuation of the background assuming Poissonian behavior.



In the (extremely probable) event that we fail to make a 5 sigma detection, we will check for a less conclusive but still interesting result.

The following would have a statistical significance of greater than 4 sigma, but less than 5 sigma:
- One 6 event window in the 100 second search
- Two independent 5 event windows in the 100 second search
- One 4 event window in the 1 second search

The following would have a statistical significance greater than 3 sigma, but less than 4 sigma:
-One 5 event window and at least one 4 event window in the 100 second search.
