-====== Severity ====== 
-We cannot afford losing any triggered data. For absolute x-section measurement GRETINA efficiency is crucial. 
- 
- 
-====== Problem ====== 
-For S800-GRETINA data with GRETINA self-trigger only we find S800 events in Global.dat without corresponding GRETINA event. 
- 
-== Size of problem (from Scott'​s email)== 
- 
-  In a low rate file, the following event counts were found: 
-  ​ 
-       ​11,​886 coincident events (s800 and gretina present with correlated timestamp) 
-       ​719 ​   s800 only events 
-       ​15 ​    ​gretina only events (now fixed in S800 daq) 
- 
-====== Progress ======
