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.LD-DEADLINK-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.

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).
