In 1986 Witt & Schild studied the optical emission of selected bright nebulae. Comparison of the data to a model led the authors to conclude the nebulae have too high a level of I-band emission to be explained solely by the scattering of starlight. The excess is explained as a broad band I emission which originates in the nebulae. This phenomenum is known as Extended Red Emission (ERE). Given Witt & Schild's data, the model they employed, and the estimate of observational errors, I've reached a different conclusion: Witt & Schild's observations are compatible with classical scattering and therefore cannot be used to prove the existence of ERE.
