((a), (b)) Fe XVI 262.98 Å intensity and Doppler velocity maps. ((c), (d)) Fe XIII 202.04 Å intensity and Doppler velocity maps (Fe XII 195.12 Å intensity and Doppler velocity maps are not shown here as they are similar to the ones of Fe XIII). The sampling times of the EIS slit are added above ((a), (c)). ((e), (f)) Synthesized AIA images simulating the EIS slit scanning mode for comparison. 131 Å is red, 171 Å green, and 211 Å blue in panel (e). To align with EIS observations, they have not been rotated like in Figure 1. The dashed line at the bottom left corner encloses the extended blueshift area in panel (d). The magenta dotted line is for the longitudinal velocity profiles in Figure 4.
