Hello Roger, These results are a little strange...I assume day 0 is so low because you did the delay by date and if the original quake was late in the day, there would not be much time for a following quake the same day. The first 10 days are in the mid 300s, the next 10 days in the mid 400s, and the last 10 days average over 500. With such large numbers, I would expect the numbers to be more uniform.
So, what do you, Roger, make of this? Are you pretty sure that the program worked OK?
It looks like my observation of two or 3 M6 quakes in the same day may not be correct.
