Abstract:
    We present LTE chemical abundances for five red giants and one AGB
    star in the Galactic globular cluster (GC) M5 based on high-resolution
    spectroscopy using the Magellan Inamori Kyocera Echelle spectrograph
    on the Magellan 6.5m Clay telescope. Our results are based on a
    line-by-line differential abundance analysis relative to the
    well-studied red giant Arcturus.

Description:
    Observations were carried out during six nights in 2003 July using the
    Magellan Inamori Kyocera Echelle (MIKE) spectrograph at the 6.5m
    Magellan2/Clay Telescope.
