Abstract

In the course of the homogeneous spectroscopic study of globular clusters in our Galaxy, we revisit the strategy of measuring equivalent widths (EWs) for the large set of data in a consistent manner. In our presentation, we show comparisons of the EW measurements from various approaches and environments for over two thousand lines in Arcturus and discuss the implication in our future study.
