4) me too, what is the proper name of the longitudinal difference between the two locations? I think it is not t (the hour angle), which can have either sign. I'd be glad to make the instruction most clear and understandable even for a novice.
Not trying to be smart but doesn't dlong = long1 ~ long2?
