Scientific paper
Our sample stars were selected from the Hipparcos catalog (I/239) by applying constraints on color, based on the color-Teff calibrations by Ramirez & Melendez (2005ApJ...626..465R), corrected by suspected zero point errors (Casagrande et al., 2009, submitted), trigonometric parallaxes, and literature values for [Fe/H] and chromospheric activity, if available. About 100 stars satisfied our selection criteria and, given our observational constraints, data for 64 of them were acquired. We also observed the asteroids Vesta and Ceres as solar reference.
