    Dear Paul,


    Thank you very much for publishing your computation results.

    They quickly enabled me to check that my own Ephemeris results are very close from your values - and well inside my own +/- 6" minimum accuracy. Actually I find values differing from yours by under 1" for the Moon and by under 0"5 for Venus.

    It has been recognized that phase effect can not be solved with a common definition which can satisfy everybody. Up until about one year ago, I used own derived formula, which I replaced by a formula derived by one NavList Member who - through integration - found a slightly different value than the one I had been using. And so far, so good ...

    Thanks again for your results which I am going to print and compare with mine. I can already see that both our results seem extremely close anyway.


    Best Regards from

    Kermit
