Hello,

problem solved by myself. I had already the "neocp.tdf" file in my guide
directory but only now I realized that I have not only change the file name in
line 6 (which is for NEOCP) but also in line 143 which is the entry for the
Horizon (JPL) Ephemeries.

The side track difference is only between 17 arcmin and 0 arcmin, but the along
track difference is 35 deg in PA 250 deg!
