    Re: Another "emergency navigation" sight reductionmethod

    Andres,

    this is the paper based on which I base my warnings re: Ageton.
    I fear people are not sufficiently aware of this problem.
     
    Of course, this warning applies to all Ageton derivatives such as
    S-tables and N(x). A very similar error occurs with Dreisenstock.

    This and other errors will not occur with any sin - cos SR if done straight
    i.e. if not done with logarithms.

    hav-DONIOL is a sin - cos SR expressed in hav(x) and done straight.
