One fixed cutoff and the actual dyadic heat metrics at nearby poles

  1. def OAI.RegularPointCoordinates.dyadicHeatGramAt line 22

    Source documentation

    The cutoff remains fixed while the heat pole varies.

    The lower mass bound also remains centered at the heat pole.

    Source documentation

    The upper mass envelope is centered at the pole, independently of the center of the one fixed cutoff.
