   BAA (70) seems to be misasigned (isn't it GSC2394.150?), but others
are in pretty good agreement with Tycho V and ground-based V.  It seems
that Tycho (Hipparcos) V is enough acceptable down to 10.5.

             BAA?   GSC    HIP-V TYC-V  B-V  ground-based measurements
                    1.1                Tycho
