    Re: Sight reduction using a calculator's POL (arctan2) key - Revisited

    Tony,

    Very true. I have decided to us variables D (declination), A (assumed latitude), and M ( meridian angle LHA).

    The short hand formula: Pol(TD CA - SA CM , - SM)     aC Ans CD = Hc

    T (tangent), C (cosine), S (sine), a (arc), Ans (answer), and Hc (calculated altitude).

    To remember the pol formula I will use a football theme: Touch Down CA lifornia - SA CMontana , - Score Montana

    Dear Greg,

    If you put all the values in the registers (A, B, C, etc) not only your cheat-list will look nicer - it will be easier to repeat calculations.

    Warm regards,
    Tony
