Brian;

I forgot to mention that the program I sent to you uses the quakes in the main array for the probability calculations. Normally I would read the big quake file for each prediction but that takes 15 minutes for Amit's 226 predictions versus 5 seconds this way.

It might make a difference if locations were an issue since the array contains only the biggest quake for each day regardless of location but that doesn't matter in this instance.
