Hectospectra of young clusters in M31. Spectra of clusters disputed as real by Cohen et al. (2005), the average of three young clusters verified by ACS images, and the average of single, blue supergiant stars as a comparison are shown. If the disputed clusters were in fact merely a few stars mistaken for a cluster, their absorption line widths, particularly the Balmer lines, would be narrow as seen in the blue supergiant spectra. These spectra have been Gaussian-smoothed and have had their continuum shapes removed for ease of display.
