OAI.RegularPointCoordinates.dyadic_regularizer_le_working_radiusline 62Source documentation
The scalar regularizer has a uniform bound over the complete finite range whenever its outer dyadic radius lies inside the working radius.

OAI.RegularPointCoordinates.dyadic_regularizer_le_geometricline 74Source documentation
Keeping the dyadic room in the estimate makes the regularizer vanish at fine scales even when the working radius and regularizer are fixed.
