Dear Bill.
My astrometic program uses MPCORB minus the cr. Can Guide8 use MPCORB
as well as MPCORBcr. I update this 9.4 MB zipped file every week and
I always have the MPCorb switched on. Ocasionally two small crosses
appear for one asteroid. With high zoom they seperate and when one
looks at the data the one is large, from the MPC and the other is the
one that came with the Guide8 CD. Can the smaller asteroid data set
be switched off in favour of the larger new updated orbits.
Best wishes John.
