Hi all,

Well, it was another dinky little burst, 1-over-threshold, in SM 2 only.
Supernova -- not.

The most probable explanation for the increase in alarm rate is that the good
hit rates increased after the last LUT iteration (as they should have,
in fact-- I've been increasing rates of low-rate tanks).

Anyway I have lowered the probability threshold a little, to 3e-6.

Kate.
