Scientific paper

Relationships between stellar integrated fluxes and the photometric indices B, V, I, K are discussed. Formulas based on a recent database of measured integrated fluxes are derived; these may be used to determine integrated fluxes for interstellar extinction A(v) = 0.0 from sets of values of V and V - K, or V and B - V, or R and R - I. A representation with an accuracy of the order of 2 percent or better is attainable. A table of corrections for interstellar extinction is given.
