6. 2 μm includes the speckle pattern from surfaces with a structure of the order of tens of micrometers, as many matte metallic coins do, as well as the glory observed around one's shadow when standing in a mist with the sun at one's back (due to water droplet diameters being of the order of tens of micrometers).

8. The term "intensity" is avoided in referring to the EMCF because "intensity" often connotes a measurable nonnegative quantity, whereas the EMCF can be negative.
9. The terrestrial solar spectrum can vary significantly with atmospheric conditions. We note, however, that when a typical clear-sky midday midlatitude spectrum is used in Eqs. (5) and (7), there is no noticeable change in the results plotted in Figs. 1-4.
