Results of spectral modelling of stars: Tables showing how much spectral line strengths change (in Ångstroms or magnitudes) when particular elements are increased by a factor of two in abundance in the spectra of different star types. The line strengths are those defined by the Lick standard wavelength ranges (e.g. see http://astro.wsu.edu/worthey/html/index.table.html ). The spectral models are from three different approaches (labelled as Conroy, Coelho and CAP). Details will be published by Adam T. Knowles (PhD thesis in preparation).
