Coronal emissions and Doppler shifts seen in Fe XII. Left panel: region of interest showing two long loop structures, which are almost perpendicular to each other. The focus is on the southern one since it shows the stronger upflows. It is twice as long as the other one. Central panel: intensity of the Hinode/EIS Fe XII line, the southern loop starting at around [−80″, 90″], where it is the brightest. Right panel: Doppler velocity from the Fe XII line, showing that the starting point of the southern loop is a region of strong upflows. We define the upflow region with a −6 km s⁻¹ contour, which is drawn in blue.
