So, please correct me, the legal state (to Tycho2) is:

Files: deepstars.dat
Copyright: 2008 Akarsh Simha <kstars-devel at kde.org>, Jason Harris <kstars-
devel at kde.org>

X-Original-Data-Copyright: 2000 E. Høg, C. Fabricius, V.V. Makarov, S. Urban,

X-Reference: Astron. Astrophys. 355.2, P L19-L22 (2000) :
             The Tycho-2 Catalogue of the 2.5 Million Brightest Stars.

or must I delete X-Original-Data-Copyright and X-Reference and add something 
like

X-Original-Data-License: Public Domain by USNO

Moreover, the data you used to compile deepstars.dat does come from the 
published Tycho2 catalogue (copyright Erik Høg et al) or directly from raw 
USNO data?

That is, should I cite Høg or ESA or just USNO? I must confess I'm a bit lost, 
since the Tycho2 name suggests citing Høg and ESA.

That's work for another Debian maintainer ;) but as soon as this is settled 
for Tycho2 I will contact him in order to be sure.
