Figure 8. (A–B) Setation vectors x= (x_i) for limbs of the remipede Speleonectes tulumensis.

(A) specimen A, (B) specimen F. The polynomial regression trendlines (0.158 − 0.212i − 0.163i² − 0.004i³ − 0.059i⁴ for specimen A, and 0.2 − 0.271i − 0.217i² + 0.04i³ − 0.028i⁴ − 0.029i⁵ for specimen F) are given in green. Horizontal axis: limb number i. Vertical axis: the value of the setation vector component, x_i. (C) Setation vectors for limbs in one scale. Horizontal axis: limb number i. Vertical axis: the value of the setation vector component, x_i. Coordinates of limbs in specimen F are stretched in such a manner that length of vector, in effect the number of limbs, for specimen F matches that of specimen A. Red, specimen A; blue, specimen F; green, the polynomial regression trend line (0.713 + 0.143i − 0.012i²).
