Sky2000 is a multi-sourced compilation done by a NASA based fellow
(well, he was NASA based, dunno about now).
It's remit (was) to collect as much data about any star as possible.
Whether that is a critical compilation or merely a SIMBADesque linkage
of data I don't know.
As Arne notes though, nothing new, just taken from other sources.
