Comparison between the distribution of S-complex PSTF potential members and S-complex background families. Top: V shape of Flora family (in blue) in a plan versus a. Flora’s members are shown in black. The red points represents the PSTF potential members that are outside all V shapes. The blue, dark green, and orange points represent asteroids that are inside Flora, Euterpe, and the Massalia V shape, respectively. Bottom: distribution of PSTF potential members compared to the typical distribution of members of Flora, Euterpe, and Massalia families. The blue, green, and orange rectangles represent the border of Flora’s, Euterpe’s, and Massalia’s regions, respectively.
