    We've been down this path before. Whatever frame of
    reference/model/fiction you choose to embrace, a 15d change in Sun
    GHA/LHA (corrected for v in the NA) does *not* equate to a 15d change in
    azimuth--except in rare special cases.
    
    More so for the moon. 4 hours do not equate to a 60d change in azimuth,
    nor LOP's at right angles to the "towards" or "away" azimuths.
