...discoveries

After submission of the originar version of this paper Rubenstein & Bailyn (1996) reported an independent discovery of variable V8. We note that the equatorial coordinates of the variable provided by these authors are erroneous. Moreover, Rubenstein & Bailyn report significantly larger values of B-V and 26#26 for V8 than those listed in Table 2 (click here).
