    Sorry about that. It is in such common use as an error description by
    programmers and alpha geeks in the the Purdue area, I thought it was
    universally known.  Another common acronym in the software industry,
    especially with support folks, is "DSO Error."  DSO being "dumb sh-t
    operator."
    
    Thank you for the excellent description of the process.  As other list
    members have mused, I too find it rather amazing that it was almost a
    century after the on-board chronometer was invented that Sumner stumbled on
    and published the concept of the celestial LOP.  One would think that since
    it was in most cases a running fix, and latitude was often determined by DR,
    that someone would have done a couple of "what ifs" with different latitudes
    long before and noticed the relationship.  A great case of mind set blinding
    one to options.  My feeling has always been that creativity is a momentary
    cessation of stupidity.
