This distribution of aa200 includes an executable MSDOS version
of aa200.exe that reads ephemeris files generated by the numerical
integration program ssystem.exe (from the archive file de118i.zip).
A very short ephemeris file de118i.out is supplied here for test purposes.
You can execute the MSDOS command
  aa200 < de118i.que > temp.tmp
to run a test.  Compare the results in temp.tmp with de118i.ans.
The reason for including this version by default is that you don't
have to buy anything or download any huge files.  You must, however,
find de118i.zip and use it to create an ephemeris file.

To read JPL's ephemerides, get a C language compiler and recompile
aa200.exe, after configuring the source code for your computer and for
the particular JPL ephemeris you want to read.  The JPL ephemerides can
be obtained by ftp from navigator.jpl.nasa.gov.  Warning: the files
are quite large!  For the files currently on their ftp site, you will
want to enable the definition DE405 or DE406 in the makefile.

For the JPL ephemerides distributed on CD ROM by Willmann-Bell
publishing company, use the definition DE406CD or DE405.
