VizieR Online Data Catalog: EW measurements of 6 Segue 1 red giants (Frebel+, 2014)

We observed five of our six target stars with the MIKE spectrograph (Bernstein et al. 2003SPIE.4841.1694B) on the Magellan-Clay telescope in 2010 March and May, and 2011 March. Observing conditions during these runs were mostly clear, with an average seeing of 0.8" to 1.0". MIKE spectra have nearly full optical wavelength coverage from ~3500-9000 Å. A 1.0"x5" slit yields a spectral resolution of ~22000 in the red and ~28000 in the blue wavelength regime. We observed the final star in the sample, SDSS J100742+160106, with the HIRES spectrograph (Vogt et al. 1994SPIE.2198..362V) on the Keck I telescope on 2010 April 1. The observations were obtained with a 1.15"x7" slit (providing a spectral resolution of 37500), the kv389 blocking filter, and a total integration time of 3.6 h.
