The case name is from the picture marking (the letter) in Figure 1b for A2-A6, and data not shown for the remainder, and the number indicates the pair in the picture, from left to right. The mother's length L2 is assumed as 190 cm. No error estimates are presented as these values are taken as indicative only.
