A collection of 24 samples of size 120 on the arch spiral from which a
persistence diagram is computed using the TDA::ripsDiag() function with
maxdimension = 2 and maxscale = 6. Each diagram has been generated using
the tdaunif::sample_arch_spiral() function with the following parameters:
n = 120, arms = 2`` and sd = 0.05`. The seed was fixed to 28415.
