ASSUMPTIONS. “In a DC field of, say, oxygen partial pressure (PO2), one can predict with some reliability, r(PO2), what the actual PO2 at a particular location in the mound might be, irrespective of time. Indeed, that is the very nature of a DC field: it contains within it no dimension of time. What is mapped in an AC perturbation field, in contrast, is the likelihood of a particular time-dependent change of PO2, that is dPO2/dt. For sake of brevity, let us call this φ (= dP/dt). Any location within a transient perturbation field is characterized by some probability distribution, r(φ). Within the mound, r(φ) is broad at the periphery, and tends toward peaked and skewed to low frequency in the center.”
