Abstract

Spectrophotometry observations (resolution 8A) have been obtained for nine Draco giants with the IIDS scanner on the KPNO 4 m telescope. A preliminary analysis using K-line equivalents widths shows an order of magnitude range in metal abundance: from +0.5 to -0.5 with respect to [Fe/H] of the giants in M92. The giants of Zinn’s B branch are more metal-poor than those on his A branch but the difference is larger than he deduced.
