[Nml] H.O 211 glitch?


Subject: [Nml] H.O 211 glitch?

Is anyone familiar with H.O. 211 (Ageton)? It is still my favorite
manual method, and I have done hundreds of sight reductions that work
out fine. However, this one is driving me crazy. When I use the
computer or any other method, I get the expected Hc = 38d 30'... but
when I use H.O. 211, I get 38d 53'. Here is the particulars:

GHA 91d 52'W
Long 80d 06'W
LHA 9d 46'W a1 77048
Decl 9d 22'S +b2 583 a2 78847
               a3 77631 -b3 617
                          a4 78230
K 9d 30'S
Lat 40d 58'N b3 617 a3 77631
K~L 50d 28 +b5 19618
                          a6 20235 38d 52'?

Anybody see anything I am doing wrong?
