Top panel: non-photospheric Ca II K (black continuous line) and H (black dotted lined) feature profiles of HD 131835. Ca II H has been displaced 0.05 relative units for clarity. Both Ca II features are fit with three and two Gaussians, respectively, plotted with blue dash-dotted lines; the blue continuous lines are the sum of the Gaussians in each case. A 3σ error bar is also plotted in red. Bottom panel: Na I D2 (black continuous line) and D1 (black dotted line) profiles.
