@TOT LOSS

• The total loss for fiber. If the total loss is -1, means the total loss is depends on the situation.
• Is store as tot_loss in the fortran code.

example

@TOT_LOSS
-1

Which mean the total loss is depends on the situation like formula below.

Formula:total loss = @LENGTH * @LOSS

Note:
prob = 10**(-(@INSERTION LOSS (FIBER) + tot_loss)/10.0)
If the RANDOM_NUMBER bigger then prob, the photon will regarded as death.
