Combining this spectrum with optical and UV spectra from the literature, we show that the unusual reddening noted by \\citet{veilleux13} is explained by a reddening curve like those previously used to explain low values of total-to-selective extinction in SNe Ia. The nuclear starburst may be the origin and location of the dust. Spatially-resolved emission in the broad absorption line trough su","authors_text":"Adrian B. Lucy, Donald M.
