Pub. No. 229

Sight reduction tables for all celestial bodies. Large, hardbound, maroon volumes, with answers given to the nearest 0.1', although this extra precision requires an extra step in the d-correction to the calculated height (Hc). The layout is slightly different from Pub. 249, but the basic use of the tables are the same except for the d-correction step at the end. Official governement hard copy editions sell for about $47 per volume (15 of Latitude per volume), commercial copies in paperback (slightly reduced in size) cost about $20 per volume. Note that these do not go out of date. If you find some in a used bookstore or swap meet for a good price, they will do the job just fine. See Sight Reduction, Sight Reduction Tables, and d-corrections.
