[G12] g12 triggers

[Andrea Celentano]

Dear g12,
I am looking at the trigger efficiency of trigger bit #5 (STxTOF x 
(ECPx2)).

Before doing so, I wanted to do some checks on the way trigger bits were 
reported in the output banks.
I have taken from tape a single file from run 56541 (file A00), and I 
opened it via bosdump, printing HEAD, TGBI and RC26 banks.

According to g12 note (table 2 pag. 5), for this run trigger bits 1..6 
are MORA x (STxTOF)_i x (STxTOF), without any prescale and without L2.
Trigger bit 8 is MORA x (STxTOF)x2.

Therefore, for any event with one of trigger bits 1..6 set, trigger bit 
8 should also be present (for example, if trigger bit 1 is set, it means 
that MORA is TRUE, and that there are two sectors with STxTOF, one of 
which is sector #1: trigger bit 8 is also satisfied for this event).

However, this is not the case for the events I am scrutinizing. I report 
to you some events showing this issue. I also CC this to Sergey and Ben, 
so that they can provide further input to the discussion.


*EVENT:*
Version:        0
Run:            56541
Event:          858
Type:           1  (physics data)
ROC:            0
CLASS:          14
Trgbit:         0x5405        --> bit 1, bit 3, bit 11, bit 13, bit 15. 
By the way, what are trigger bit 13 and 15? They are not reported in 
table 2.
