Just did a couple of sample sight reductions using only 4 place haversines and got within 1' of smart phone app reduction for following:
Lat 1° 30' N Lat + Dec = 2° 30'
Dec 1° 0' S Lat - Dec = 0° 30'
LHA 75° 0'
Hc 14° 58'
Lat 20° 30' N Lat - Dec = 0° 35'
Dec 19° 55' N Lat + Dec = 40° 25'
LHA 65° 0'
Hc 29° 26'
