Scientific paper
In Gratton and Sneden (1986) we discussed the abundance of light elements (Na, Mg, Al, Si, K, Ca and Ti) and Ni in 46 halo stars. The chemical abundances were based on stellar atmosphere analysis of equivalent widths obtained with the McDonald 2.7 m and La Silla CAT telescopes. In this paper we present the observational material and a tabulation of the equivalent width data.
