indicated a constant difference (check-comparison) of ΔV = +0.536, the standard deviation of a single observation being ±0.005. The variable is almost 2 mag fainter than the composition and shows significantly more scatter. Each observation of the variable has been corrected for differential extinction and transformed to V of the U B V system using the color difference (in the sense variable-comparison) Δ(B-V) = +0.34 reported by Williams et al. (1990).
