A spectroscopic survey of faint, high-galactic-latitude red clump stars. I. The high resolution sample. Valentini M., Munari U. <Astron. Astrophys., 522, A79-79 (2010)> =2010A&A...522A..79V

We acquired data of the program stars of high signal-to-noise ratio and high resolution with the Asiago Echelle spectrograph. We obtained radial velocities by applying cross-correlation and atmospheric parameters via chi2 fitting to a synthetic spectral library. Extensive tests were carried out by re-observing with the same instrument a large number of standard stars taken from a variety of sources in literature. Description: File arcs_a.dat contains name, available photometric data, additional spectroscopic and calculated parameters of observed 207 red clump stars, 66 observed also in a second epoch. File arcs_b.dat contains the same data for 70 brighter red clump stars, observed for calibration purposes, 35 observed in a second epoch. File arcs_c.dat contains the same data for 55 test and calibration stars taken from literature. File Summary:
