Vision: The Additivity Law Made To Work for Heterochromatic Photometry with Bipartite Fields

Additivity failures are common in heterochromatic photometry when the usual criterion of equal brightness is used. Using instead the criterion of a minimally distinct border between two precisely juxtaposed fields, we found that the additivity law holds.
