Some of you have asked about the change I made to make it so one could send
long pulse beam to BAS-1 only.  i.e. leave the long pulse that goes to BAS-1 on
while deactivating trig lc00 306 on the pulses that would otherwise go to ESA.

If one looks at trig lc00 306 conditional expressions for beam 1, it looks
like:

LC00    Beam 1     TRIG 306
  1. Condition     no_gun_perm|e154witness
     Timing value  deact
  2. Condition     ~DUMP_BAS1
     Timing value  *+ESA_LONG_PLS

Now: ESA_LONG_PLS is a timming variable, and one of the valid values of the 
TMVA is the deact value.  So The timing value for condition 2 is either
 * + 0.0 when the TMVA is active OR * + DEACT when the TMVA is deact. 

So, with the TMVA deactivated the condition ~DUMP_BAS1 gives a value of DEACT
and the long pulse laser trigger is deactivated when DUMP_BAS1 is not
broadcast.

Remember one can use the conditional expressions panel to frist select and then
react/deact TMVAs.

Enjoy,

William.
