Description:
The table 1 lists photoelectric UBV measures for 78 stars in the open
cluster NGC 6025. Distance and age estimates derived are 760pc and
100Myr. The brightest star, HD 143448, is a known emission star and
is very probably a member of the cluster.
Accurate positions and identifications of the stars were added by
B. Skiff (Lowell Observatory) in November 2009.

Note (1): Sources are:
M = 2MASS (2006AJ....131.1163S 2006AJ....131.1163S, II/246)
T = Tycho-2 (2000A&A...357..367H 2000A&A...357..367H, I/259)
U = UCAC2 (2000AJ....120.2131Z 2000AJ....120.2131Z, I/289)
Note (2): NM = non-member. The (*) indicates errors detected:
* for star 45: the star marked on the chart is a blue object whereas
the UBV colors are for a red one; the correct object, confirmed in
V using ASAS-3 and for color from 2MASS J-K, is slightly to the
northeast. Kilambi (1975PASP...87..975K 1975PASP...87..975K) shows photographic UBV
for the bluer star (V=12.81, B-V=0.49, U-B=0.49).
* for stars 56 and 62: the Feinstein table must have typos for the V
magnitudes, corrected here with reference to Kilambi and ASAS-3.
