The following equations were misprinted in the .gif. For some reason the asterisks (multiplication) were changed into up arrows (exponents).
a=asin(sin(T)*cos(Dec)/sin(S)) tan(e/2)=[tan((a+90-Dec)/2)*sin((S-T)/2)]/sin((S+T/2)) Finally, e=2*atan[[tan((a+90-Dec)/2)*sin((S-T)/2)]/sin((S+T/2))] Bill G.
