Notes. 

(a)

The average of the distances quoted in An et al. (2007; 8.93  ±  0.08 plus a +0.02 correction), Hoyle et al. (2003; 9.08  ±  0.18 plus a +0.09 correction), and Pel et al. (1985; 8.95  ±  0.10 plus a +0.08 correction).

(b)

The average of the distances quoted in Turner et al. (1992; 11.11  ±  0.02 plus a +0.09 correction), An et al. (2007; 11.04  ±  0.05 plus a +0.02 correction), and Hoyle et al. (2003; 10.94  ±  0.14 plus a +0.09 correction).

(c)

The average of the distances quoted in Turner (1986; 9.78  ±  0.03 plus a +0.09 correction), An et al. (2007; 9.65  ±  0.06 plus a +0.02 correction), and Pel et al. (1985; 9.84  ±  0.10 plus a +0.08 correction).

(d)

The average of the distances quoted in An et al. (2007; 11.51  ±  0.13 plus a +0.02 correction), Hoyle et al. (2003; 11.33  ±  0.18 plus a +0.09 correction), and Walker et al. (1985a; 11.15  ±  0.3 plus a +0.09 correction).

(e)

The average of the distances quoted in An et al. (2007; 11.03  ±  0.08 plus a +0.02 correction), Hoyle et al. (2003; 11.18  ±  0.12 plus a +0.09 correction), and Walker et al. (1985b; 11.05  ±  0.10 plus a +0.09 correction).

(f)

Three distance determinations have been considered: Turner et al. (1998; 11.08  ±  0.03 plus a +0.09 correction, adopting E(B − V) = 0.75), An et al. (2007; 10.74  ±  0.21 plus a +0.02 correction, adopting E(B − V) = 0.57), and Hoyle et al. (2003; 11.34  ±  0.21 plus a +0.09 correction, adopting E(B − V) = 0.90). The adopted distance is the average of the three, but the dispersion is large. This is likely due to the very different reddenings adopted. If a correction is made to a reddening of 0.75, adopting Δ DM/Δ E(B-V)  ~ 2 (An et al. 2007), then the average becomes 11.14 with a very small dispersion.

(g)

The average of the distances quoted in Turner et al. (1993; 11.26  ±  0.10 plus a +0.09 correction), and Hoyle et al. (2003; 11.18  ±  0.16 plus a +0.09 correction).

(h)

The average of the distances quoted in An et al. (2007; 12.46  ±  0.11 plus a +0.02 correction), Hoyle et al. (2003; 12.58  ±  0.14 plus a +0.09 correction), and Romeo et al. (1989; 12.65  ±  0.15 plus a +0.08 correction).
