Illustrative Spectra

Below are examples of high signal-to-noise spectra for a variety of stellar types, highlighting major spectral features. The stellar parameters indicated for each star:

• effective temperature (T_eff),
• surface gravity (log g)
• metallicity [Fe/H]

are derived from the observational data via the SEGUE Spectral Parameter Pipeline (SSPP).
