Disregard that. Just go to a little web site I have set up:
http://home.earthlink.net/~s543t-24dst/sofajpl/
Complete source code for the DLL is online there too, except for the
SOFA Fortran code, which is at the SOFA web site.
In addition, I have put most of the interesting files into HTML form,
readable with your browser.
The main demonstration program (sofajpl_demo2.c) has been improved from
the one I sent out by email:
1. The topocentric star position computation compatible with MICA 2.0
now gives the topocentric apparent RA & dec. Formerly, it gave the
*geocentric* RA & dec, and *topocentric* azimuth, zenith angle, and LHA.
All the values were correct, but it makes more sense to have
everything topocentric.
2. On the web I found an example of a stellar apparent place reduction,
by Patrick Wallace of HMNAO. I use the DLL to duplicate his computation.
