Synthetic Hα and Hε images at an heliocentric angle of μ = 0.5. Panels a and b show an Hα wing image for the cbh and en simulations. Panels c and d show an Hε line core image for the cbh and en simulations. The wavelength position of each image is indicated by a red vertical line on top of the averaged spectral profile at the top-right corner. The Hε images are a proxy for the line core emission and were calculated by neglecting the contribution of Ca II H.
