The horizontal and vertical accuracies are read from the GPS receiver.  It 
seams to be directly related to the number of satellites currently in 
view.  No tables!

As for WAAS/Egnos, you are correct, pressing the 3 key while in Navigation 
mode will tell you what type of fix you have.  If it is a normal fix it 
will just say: "GPS fix".  If you locked on to WAAS (North America) or 
EGNOS (Europe) it says something else.  I don't think that EGNOS is 
working properly yet though I haven't checked the European Space Agency's 
web site in a while.
