Hi Bill,
Tanks I have received, very soon, Guide 9.

Now I wish to import all my setting from Guide 8 to 9, can you give me some general instructions?

I wish also to know which "homemade" file I have to copy, example:
costlin.ove
*.mar
*.tdf and connected datafile
Etc.

In guide 8 datafile guide.dat I have:

JPL_EPH=e:\eph\de406.eph
In guide 9 we have DE422 so I think this is not any more necessary.

UCAC3_PATH=f:\ucac3b
UCAC2_PATH=d:\u2
In guide 9 we have UCAC3 directory so I think is not any more necessary.

DELTA_T=-100000,948:2715.6,573.36,46.5
I don't know if it is necessary.

Do I have to copy any setting of this file from Guide 8 to 9?

Best Regards
Dario
