OAI.PolycyclicRecognition.rescaledMapProfile_norm_leline 19Source documentation
A bound at the identity extends to a pointwise bound by the actual scaled chart distance.

The profile value at the identity is controlled by the suffix length.

OAI.PolycyclicRecognition.exists_compact_containing_rescaled_profilesline 55Source documentation
Once equicontinuity is proved, only the anchor and pointwise chart radius bounds are needed to contain all sampled profiles in one compact set for locally uniform convergence.
