V magnitudes and B-V colours with corresponding uncertainties are from
Hipparcos (stars 1-2) and Tycho-1 (3-5, 17) catalogues, and CCD
observations by A. Henden, USNO (stars 6-16). The last column contains
star identifications by B. Sumner, which sequence is available from
ftp://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/sumner/bzuma.seq
The brightest star (1 = HIP 43485) is double (Struve 1275, sep. 2".0),
combined magnitude is given. Star 8 (GSC 3811-1354) appears to be
somewhat variable and should only be used with care.
