    Re: Greg's article on hav-Doniol in "Ocean Navigator"

    here is a copy of the Azimuth Diagram.
    Should you find this one is in error, too,  please let me know.

    As for my chosen method for multiplication I have trumpeted
    the advantages of the Vedic / Butterfly method as you might know.
    Let me do it here again:

    * Produces just the needed leading digits if so desired -
     i.e. the 4 digits for hav-Doniol therefore saving superfluous work.

    * No need to memorize carries.

    * Orderly structure; leads to reliable error checking.

    I am by nature a terrible "multiplicator". With this method I have reduced my error rate
    immensely. Greg Rudzinski, however, is a gifted number cruncher and thinks not much of this method.  :)

    Hello Hanno,

    I cannot find 
    my printed copy of your Azimuth Diagram, and I printed another one, but something is wrong, testing it with: dec = 30, LHA = 40, Hc = 50 -> Z = 58 not 60.
    I think is an issue with the migration from WXP to W7, and the distortion of the scale while printing. To avoid this, is it possible to obtain a PDF copy of the Zn diagram?
    The PDF allows you to print without rescaling

    For my is very useful the repetition of the scales: left = right, top = bottom, this makes me easier the plotting of the lines with only a ruler.

    best regards,
