RE: [guide-user] "Go to Asteroid" problem

Arturo R Montesinos Sep 22, 2004

Guide 8 only installs to the hard disk the osculating orbital elements for
asteroids found on CD 1, which end on that date.

There are more orbital elements on CD 2, in a folder named ASTEROID.

Simply copy folders "2453" to "2460" from the ASTEROID/ASTEROID folder in
the second CD to your hard disk (under the ASTEROID folder of your Guide 8
installation), and Guide will be able to calculate accurate asteroidal
positions up to the year 2023.

If you should ever need to extend the asteroid data further in time, or
you're particularly interested in where a newly discovered asteroid from the
MPCORB table will be a few years from now, Bill has a program in his (old?)
web site, at http://home.gwi.net/~pluto/integrat.htm that takes an
MPCORB-format file, numerically integrates the asteroids' positions up to
another date, and writes out a new MPCORB-format file with the osculating
orbital elements updated to the new epoch.

Asunto: [guide-user] "Go to Asteroid" problem


Guide Users,
Using Guide 8 on my PC running Windows 98, I have a problem with "Go
to Asteroid". As long as the time is 2005 May 9, 11h 59m 59s or earlier,
it works well. But if the time is May 9 12h 00m 00s or later, I get a
message "Not an Asteroid". This is for any asteroid number. Incidentally,
that time is JD 2453500.5. I replaced Guide8.exe on my hard disk with
Guide8.exe from the CD 1, but the problem remains. What's going on?????
