Hi Bill.
Thnak you for comment for Pluto's occaltation with UCAC2 star.

I know Asteroidal occanltations and Pluto's occaltations are very serious.
They request high accurate position data of planet and star.

I read CMC-14 data are higher accurate than UCAC2 stars.
So this case ( event on 18 Mar. ) gave me satisfaction.

>_Usually_, I think you can trust the UCAC2 proper
>motion data... but in this case, it looks as if it's wrong.

Thank you. I think so, too. But I think Pluto's occantations are rare case.
We need to be interpreted serious.
