Welcome to Kazumi's Trigger Page

Trigger Info

The trigger info recorded for each trigger is:

A 48 bit timestamp. This is zeroed at the start of the run, and should match the timestamp recorded by the LBL electronics
A 36 bit (board3 version < 12), 52 bit (board3 version = 12) trigger-type, see table
A 12 bit ID total nsum
A 6 bit OD top total nsum
A 6 bit OD upper side total nsum
A 6 bit OD lower side total nsum
A 6 bit OD bottom total nsum
A 4 bit 5 inch tube total nsum
A 16 bit number giving the total number of calibration triggers since the start of the run (board3 version < 12) which because additional trigger types after board3 version = 12

GPS triggers record the absolute time in addition to this information.
