Radius progression

Radius distribution (φ-r)

Area progression

Area distribution (φ-A)

Area-radius-ratio

Area/Gravity center radius (rC) distribution (φ-A/rc)

Contour angle progression

Angle between the outer spiral contour and the circumferential direction (φ-α). Note, that due to the differential characteristic of the contour angle, the continuity of this distribution is decreased by one.
