You're right John, I am NOT close to 180 degree from the epicenter. I have 
put the data in over ten times. Early on, I even reverse the 177 to a 
positive number to try and get it to show phases think it was an error on 
the post. The travel time table shows 107 degrees and 11896 km. I have made 
mistakes before...particularly before two cups of morning coffee but not 
this time.
