Doppler shifts for a second region (see Fig. 15 for context) of the coordinated SPICE and IRIS observations. Panel a: IRIS data. Panel b: SPICE data. Panel c: Corrected SPICE data. This second region has a lower signal compared to the first region and a small, highly complex region (blue circle at top left of each image) that shows a strong (likely artifact) feature in SPICE but not in IRIS. Generally, the correction removes the artifacts, although the agreement with IRIS is less strong than in the first region (Fig. 13). See text for further discussion.
