Piccone & Kobulnicky 2021 Zeta Ophiuchi Spectra Dataset

Spectral data that accompanies the 2021 ApJ publication, "A Tale of Three Dust Populations: Variable R_V and Extreme Polarization Along Sightlines Toward zeta Ophiuchi." Formatted in a FITS table, this provides the optical spectra of 27 stars surrounding zeta  ophiuchi, obtained with the Apache Point Observatory. This data was used in the paper to infer reddening and extinction.
