Hi All,
I have edited the Installing_Scenery page in the wiki by fleshing out the
TODOs a little more.

If someone could do something for fgadmin, that would remove the last TODO
on that page :-)

I doubt that the moon has much influence (although it slightly
deforms the Earth surface). The sun angle effect is already
contained in the other values, as well as in the
Changes to the huge compressed files should IMHO generally
be avoided. It means that, no matter how simple the change,
everyone has to download megabytes of data. In most cases
it should be enough to drop Robin a line and to wait for
the next update. (In the last apt.dat.gz one of my routine
Thanks for the processing chain.
I'll see if I find some time to look into this in the weekend. Lots of other
data processing (ant distributions, butterfly breathing, etc.) on the bench
already... :)

try to find some complicated filtering in the hope, that the
remaining data gives a simple model that's better than the
conservative setting.
Ahh, excellent. That sounds even better.
Use the Ts tag in the controller configs to specify a 'fixed'
sampling rate. Personally, I config and tune all my controllers to
run at 20Hz so that there is a good chance they'll work on
lower-end systems without causing problems on faster machines.

No, Nasal has nothing to do with it. It's only the order in

Well, Nasal has indirectly to do with it: the change in execution

i fear i'm not the right person to answer this. (at least not without doing

i don't *believe* the problem you describe could be related to the deletion of
