Description
The files in this data set contain equivalent width measures made in the course of a number of published studies for four types of objects: mid-to-late supergiants, metal-deficient red giants, subgiant CH stars, and G/K giants. The files include identified atomic and ionic species, wavelength, lower excitation potentials and log(gf) values. Subgiant CH stars in the data are late F to early G stars whose spectra exhibit strong CH, Sr II, and sometimes Ba II features.
