Notes. The meaning of the symbols is the same as in Table 4.

^(a)

LC1=(B − R)/(B + R + V) + 0.47M_V, is the linear combination of the pair of listed parameters displaying the strongest correlation with A_rot.

^(b)

LC2 = M_V − 1.73[Fe/H], displaying a correlation with A_rot nearly as strong as LC1.
