Michael;

maybe this will help.

I've written a new program which will find best-fitting quakes. It takes a center point, radius, date and mag. range and finds 3 quakes; the closest one in time, the closest one in space and the biggest one around.

It's currently set to double the radius, an extra day on each end and 1/2 unit of mag. on each end. These determine the search parameters.

I'd like suggestions on those parameters; too big, too small, what do you think? And which one is the best fit; closest in space, time or largest? Or would you want to see all 3?

This is a tool to help refine your method. Probability will be determined by where the hits actually fall in the ranges.
