Notes. No interstellar extinction was applied to the magnitudes. Effective temperatures found by Asplund et al. (2000). The related stars are close to the Galactic plane ( deg).

(a)

From Schlegel et al. (1998) map, using 4-pixel interpolation.

(b)

Calculated using E(B − V)/AV = 3.08.

(c)

Values in parentheses are the reddening E(B − V) and the extinction AV determined using the photosphere.
