Hi Siebren,
In Guide 8, if you're running the current version downloaded
from the Web site, you _ought_ to see this...
http://www.projectpluto.com/update8.htm#orbital_binaries
...and I do see both components, and "more info" gives a little
ephemeris showing the changing distance/PA.
However, you made a reference to Guide 7, which doesn't have
this improvement. As the translator for the Dutch version of Guide,
you ought to have received Guide 8 automatically (just checked, and
you're marked correctly as an "auto-update" in the database). If
you didn't get a copy, or just can't find it, please send me a
current address.
