Spectra from the MMT/Hectospec The MMT observations were obtained in June 2012 with the Hectospec multi-object spectrometer. The Hectospec is a fiber-fed MOS with a 1 degree FOV and 300 fibers. Each fiber subtends 1.5 arcsec on the sky which at the distance of M101 is 47 pc. We used the 600 line grating with the blue tilt centered on 4800A and the red tilt centered on 7300A. The 600 line grating gives a spectral coverage of ~ 2500A with 0.54A per pixel resolution. The total integrated exposure times were 240 minutes in the blue and 180 minutes in the red. The spectra were reduced using an exported version of the CfA/SAO SPECROAD package for Hectospec data, E-SPECROAD. The S/N varies from star to star depending on its apparent brightness, but ranges from 60 to 25. The specta were bias subtracted, flat -fielded, wavelength calibrated, and sky subtracted. The IRAF task sensfunc, in the ONEDSPEC package, was used to flux calibrate the spectra with the standard Feige-66. No Heliocentric correction was applied to the wavelength scale.
