Spectra were obtained with the M2FS and MIKE spectrographs located on the Magellan-Clay 6.5m telescope. These spectra revealed the presence of Be stars, occupying primarily the cool side of the split main sequence (MS). Rotational velocity ($v\\sin{i}$) measurements for most of the targets are consistent with the presence of two populations of stars in the cluster: one made up of ra","authors_text":"Aaron Dotter, Andrea K.
