Library of high and mid-resolution spectra in the CaII H & K, H{alpha}, H{beta}, NaI D{1}, D{2}, and HeI D{3} line regions of F, G, K and M field stars

D. Montes, E. L. Martin, M. J. Fernandez-Figueroa +2

In this work we present spectroscopic observations centered in the spectral lines most widely used as optical indicators of chromospheric activity (H{alpha}, H{beta}, Ca II H & K,…
