(1) Illustration of instantaneous irradiance or cumulative radiant exposure is achieved using a false-color rendering-mapping light intensity to color-creating irradiance or exposure isopleths .(2) The profiles could result from garnet growth parallel to Fe-Mg isopleths .(3) The rapid rates of migration of trees, evident in the pollen isopleths , remain unexplained.(4) The scene observed in false color illustrates the incident light pattern so explicitly as to delineate irradiance isopleths .(5) Only later did I realize that my success was due to the fact that I presented my results in classical ‘Margarian’ style, including isopleths and mathematical formulas.
