A set of 24 persistence diagrams computed from noisy samples of
2-armed Archimedean spirals. Each sample consists of 120 points sampled
from an Archimedean spiral, embedded in 3D with a zero z-coordinate, then
Gaussian noise (sd = 0.05) added. Vietoris-Rips persistence was computed up
to dimension 2 with maximum scale 6 using TDA::ripsDiag(). Generated
with seed 28415.
Format
An object of class persistence_set containing 24 objects of class
phutil::persistence.
