Hi Dave,

I just got the current 'neatod.dat', renamed it to 'mpcorb.dat',
and was able to find assorted asteroids in it. But (1951) and
(1922) aren't in that file. The first 90 numbered asteroids
included in the file are shown below, starting with (433) Eros
and going up to (5201) Ferraz-Mello.

I'd look at your copy in a text editor or word processor,
just to confirm that the objects you're looking for are really
in the file.
