Okay I'll stick with it ... I had a quick canter round the corral, but I'm back now.

You don't fully understand what I am doing, and I don't know about computer programs.

Should be interesting !

Duffy;

Ok, once more;

1) You have a time of interest

2) You find where sun and moon are overhead at that time.

3) when a 5+ quake happens within 30 days you look to see if the sunrise/sunset line of the quake hits the sun or moon location.

(Isn't the reverse also true? The quake is on the sun or moon's rise/set line?)

Now isn't that 90 degrees either way? Not quite because the earth isn't a sphere, but close.

Programming is fun. You tell the computer what you want in a language it understands. It does what you said and tells you the result.

The catch is that it does EXACTLY what you tell it, not what you mean. Spelling errors are devastating and very hard to find.

Now the odds on a hit can be determined by a large number of such calculations using random times for the signal, counting hits and misses. That's why we need the program; you can't do thousands of trials by hand but the computer can, easily.
