Dear Fred,
Thank you for your message of Mon Nov 28 2005 12:21:44 EST.
(It is listed on the list archive between April 2 and 3,
so I can be excused for discovering it only today:-)
I recall that you wrote (presumably in November):
>Your data look very good. I am not sure, however, that you can

>with so few data.
This was only a small sample of my data.
Small but typical. To summarize my 2 years of obsevations
I would say that I have an error of +.3 to +.7
more frequently than I dont.
And I almost never have negative errors.
The most frustrating thing is that I measure one
chosen distance of say 38 degrees night after night,
many many times, taking all possible precasautions,
and I obtain this +.3 error again and again.
Then I take Bill's Astra, and the distance is OK.
Then I take my SNO-T again and again get +0.3 error.
I think human errors are excluded here (by Bill's Astra).
Random errors are excluded by consistency of the biased results.
So what is this, I don't really know:-(
Alex.
