We present a combined experimental and theoretical study of two-color photoionization of neon, showing that the delay τa determined from one harmonic below and one above the ionization threshold largely deviates from the value expected for sidebands generated only above threshold. The variation is attributed to excited states of neon that can be effectively populated by the 13th harmonic of the XUV frequency comb.
