Steven,
I poked around aa-55 until it became obvious that you had done a
considerable amount of programming to get it to produce your lunar distance
table. C code is way beyond my capabilities, so I have retreated to the
safety of my spreadsheets.
If you want to make any form of your code available, I would be happy to
post it on www.LunarDistance.com if it is a reasonable size. Even a
simplified version that published a standard set of 8 distances for a
specified object for a specified day might be helpful. I certainly would
use it to explore what distances might be available for times when I plan to
be at sea (eg. June 14 - 17 when I know the sun is out of distance but would
have to do a lot of tinkering with my spreadsheets to figure out what stars
might be usable during the evening).
Let me know if this is a practical idea, and don't worry if it is not. We
all have to limit our volunteer programming hours.
Regards,
Arthur Pearson

Arthur,
Gordon was right that aa-54g is an older version of aa-55. I have written
some scripts (bash and awk, for unix friends) that make heavy use of aa to
select suitable bodies and compute lunar distances, and then call LaTeX to
produce the table. If people are interested then maybe I can put them on a
web site. I hasitate to share the code because I am not a professional
programmer, the code is badly documented (if at all) and not very stable
(sensitive to the version of the awk program, for example).
