Table 4. Regression polynomials for setation vectors of limbs.

j is a limb number. Polynomials are given for segments separately (Figs. 6A–6D), for sums of setae in segments (Figs. 6E and 6F), for segment vectors (Figs. 8A and 8B) and for vectors for limbs for specimens A and F given in one scale (Fig. 7C).
