Last closed-flux surface and synthetic emission in the vicinity of the coronal hole at the end of the simulations. The coronal hole boundary as defined by magnetic field connectivity is indicated by the blue lines. Photospheric driving flows have been imposed at the helmet streamer (left column) and pseudostreamer (right column). The height of the peak emission of the indicated charge states is ordered to increase going down the page. Note the greater complexity of the coronal hole boundary in the case of the driven southern boundary with the helmet streamer, compared to the northern pseudostreamer boundary.
