We present a practical diagnostic for quantifying changes to the supercontinuum spectrum of an ultrashort laser pulse undergoing nonlinear propagation. The method allows a connection to be made between a nonlinear physics phenomenon and the specific regions of the angular spectrum that it affects. We apply this method to investigate interference between third-harmonic generation and self-phase modulation.
