Pub. 249 (formerly H.O. 249) Volume 1 includes 41 of the 57 navigational stars, but for any particular latitude and 15º band of LHA of Aries there are seven "selected" stars, considered the best for observation. But at any particular latitude and 15º band of LHA, there are certainly more than those seven of the 41 available for observation. On what basis are those seven selected? I'm thinking altitude might be one factor - not too low, not too high. But that would definitely not be everything.
