I've just released a free almanac program for Windows. It's actually a
prototype for a program to compute refracted separation angles between
celestial bodies. By coincidence, when the last disussion erupted on
that subject I was already at work on the program.

My plan is to proceed via a series of prototypes. This is the first one.
It simply computes the position of one body. Before proceeding further I
want to upgrade my SofaJpl astronomical DLL, the "engine" that does most
of the hard work.

There's no telling how long it will be before I finish the separation
angle program. In the meantime, the prototype is peforming so well, why
not release it as freeware?

I do not believe most people will find this program useful. There are
already many planetarium and navigation programs, and I don't intend to
compete with them. But some of us do peculiar things and have trouble
getting what we need from mainstream apps. For example, for testing and
debugging your own program, perhaps you need coordinates in radians, or
as a unit vector in rectangular form. Or perhaps you analyze historic
data and need to work in apparent time, with precise control over delta
T. For that type of work my program may be helpful. Anyway, you can't
beat the price. No fee, no registration. Details are at my site:
