Hi,
I worked over the same IBVS issue (1668) about 6 months ago, and
noticed something odd about the photometry for star 10. It disagrees with
the data from other sources : V = 11.39 (Tycho-2); V =11.48 (ASAS-3); Uc =
11.35 (UCAC2).
The UBV data for star 10 is essentially identical with star 4. Evidently
the photometry for star 10 is simply a repetition of star 4, by mistake.
The two stars lie close together, only 2.5sec apart in RA.
Regards,
Mati
