Abundances in stars from the red giant branch tip to near the main-sequence turnoff in M71. I. Sample selection, observing strategy, and stellar parameters.

COHEN J.G., BEHR B.B. and BRILEY M.M.

Abstract (from CDS):

We present the sample for an abundance analysis of 25 members of M71, with luminosities ranging from the red giant branch tip to the upper main sequence. The spectra are of high dispersion and of high precision. We describe the observing strategy and determine the stellar parameters for the sample stars using both broadband colors and fits of Hα profiles. The derived stellar parameters agree with those from the Yale2 stellar evolutionary tracks to within 50-100 K for a fixed logg, which is within the level of the uncertainties.
