Note (1): Our running number, grouped in intervals of 0.1 in (B-V)0
[dereddened (B-V) color] and with a prefix roughly indicative of
spectral class. These numbers are continued for the Pels stars i
in Table 7b.
Note (2): Star name:
No prefix: H II number of Hertzsprung (1947).
R, S: Trumpler (1922). Sometimes denoted as TR or TS.
sk: Stauffer et al. 1991.
Ton: Tonantzintla number from Haro et al. (1982). These are the
numbers in column (1) of their Table I, and should not be
confused with the `T' designations there.
Note (3): Mean observed (B-V) value, taken from the compilation of
Mermilliod (1986), except that any Johnson & Mitchell (1958)
observation with (B-V) > 1.00 was rejected as being too inaccurate
unless no other was available. Values with a colon indicate a
poor-quality observation of Johnson & Mitchell (indicated by a
`J' in column (4)) or that the (B-V) values for that star show
greater than average variance.
Note (4): Number of independent (B-V) values used to calculate col. (3).
A `J' indicates that the only available datum was a
photographic (B-V) from Johnson & Mitchell.
Note (5): Johnson colors from Mendoza (1967) and Landolt (1979).
Note (7): Kron colors from Stauffer (1980, 1982, 1984).
Note (8): for the hottest stars, Stroemgren index from
Crawford and Perry (1976)
Note (10): Spectral type, from Mermilliod (1986), Kraft & Greenstein (1969),
Wilson (1963), Herbig (1962), Breger (1984), and Breger (1986).
Note (11): Adopted unreddened color, (B-V)0. Except for the few stars
with unusual reddening (see Table 9), these were all calculated
using E(B-V) = 0.04 magnitude, but all available colors were
used as input, using mean relations. These colors are not,
of course, precise to 0.001 magnitude but we have preserved
an extra decimal place to reduce round-off error.
Note (12): Adopted value of the effective temperature, calculated from
(B-V)0 as described in the text, and rounded to the nearest 20 K.
Note (13): Rotational velocity, from the present study, SH,
Stauffer et al. 1984, Anderson et al. (1966), and Kraft (1967).
A note of 'S' indicates a double-lined spectroscopic
binary whose v sin i values are given in Table 2. A few
other recent determinations of v sin i for some of these
stars are mentioned in the text.
