    Why in the name of all that's holy do you do that yourselves?  There are
    only two times a year, and two longitudes on earth that the sun will be 0
    declination at LAN. It will have a lower declination before LAN and a higher
    declination after LAN now and vice versa in September, so Hc and the
    slope/curve will be affected and not symmetrical.
    
    I went through the trauma of the sea monkey kit being brine shrimp in my
    youth.
    
    Then, before cel nav, the belief that the sun would rise exactly in the east
    and set exactly in the west; and the day (sunrise to sunset) would be
    exactly 12 hours long. I would check out my topo map, find a farm field(s)
    with equal elevation miles away, adjust my Silva Ranger for declination
    (variation) and wait with my binoculars for sunrise and sunset. Always
    disappointed.
    
    Now I know unless there is a bizarre and serendipitous shift in refraction
    both at sunrise and sunset it will not happen. Also that I will not get a
    pony for my birthday.
