Re: TASS database vs. other databases

[Michael Koppelman <lolife@bitstream.net>]

Why? The astrometry is good enough to use the epoch/ra/dec as a unique 
identifier and can be cross-referenced easily in SIMBAD and such. It 
wouldn't be too tricky to write a script to add Tycho identifiers or 
similar to the data.
