Beginning of ReadMe : J/AJ/131/895 Stars in the Carina dwarf spheroidal galaxy (Koch+, 2006) ================================================================================ Complexity on small scales: the metallicity distribution of the Carina dwarf spheroidal galaxy. Koch A., Grebel E.K., Wyse R.F.G., Kleyna J.T., Wilkinson M.I., Harbeck D.R., Gilmore G.F., Evans N.W. <Astron.

Here we present metallicities for 437 radial velocity members of this Galactic satellite. The metallicities and radial velocities were measured as part of a Large Programme with the Very Large Telescope at the European Southern Observatory, Chile. We obtained medium-resolution spectroscopy with the multiobject spectrograph FLAMES. Our target red giants cover the entire projected surface area of Carina. Our spectra are centered at the near-infrared CaII triplet, which is a well-established metallicity indicator for old and intermediate-age red giants. The resulting data sample provides the largest collection of spectroscopically derived metallicities for a Local Group dwarf spheroidal galaxy to date. Description: Our observations were performed in visitor mode with the FLAMES (Fibre Large Array Multi Element Spectrograph) facility at the Very Large Telescope (VLT) UT2 of the European Southern Observatory on Cerro Paranal in Chile. We observed during 22 nights spread over two semesters in 2003 and 2004.
