Roger;

I'm happy you got things sorted, getting sun and moon positions will represent crosses on a map, fair enough.  But these crosses then have to represent the point of sunrise/sunset dawn/dusk at an event time. The crosses are fixed positions, and the quakes in the test occurred at varying distances. I don't think a 90 degree distance from the crosses is going to represent what we did in the test ... does that make sense ? 

Wish I had your talent for changing the subject !
