With 128 available fibers in our observing mode, we are able to target every star in the core half-degree of each cluster that could plausibly be a solar-analog member. Our template-based spectral fits provide precise measurements of fundamental stellar properties - $T_{eff}$ ($\\pm$30 K), [Fe/H] and [$\\alpha$/Fe] ($","authors_text":"Edward W. Olszewski, Jeffrey D.
