This is reply to my post...

I put some asteroidal occultation charts they were successful observed
in Japan at
http://www.asahi-net.or.jp/~fp6m-kud/integrat2e.htm

On the case of "2004.4.18　(388) Charybdis", both of using Guide's build-in
asteroid orbit data and integrated orbit data are too far from observed
location.
I wondered why not so acculate ?

Today, I understood that reason.
Good prediction used UCAC2 star catalog.
Guide use GSC-ACT catalog for that star.

I declare integrat utility works very fine !

And I need help.
Do someone know the site where be able to download UCAC2 catalog ?

I know UCAC2 is distributing 3 CD-ROMs from USNO.
And I found "Vizier" have UCAC2 directory, but there is no dat file ( "u2"
directory ).
