Dear Tony,

I have not yet had a chance to look into the details of your interesting
question which started this thread. But regarding the ephemerides of
David Origanus (spelling! Latinized form of Trost), they are based on
the  meridian of Frankurt/Oder. There is no connection between Origanus
and Wittenberg, except, perhaps, that his ephemerides are partly based
on the tables of Reinhold, who taught there. But Reinhold's tables were
based on the meridian of Koenigsberg, Prussia. Origanus was a professor
in Frankfurt when he published his ephemerides, but prior to that he was
in Breslau.  Curiously enough, that place is 17 deg east of London. I
leave it to you what you want to make of this. I believe it is just a
coincidence.
