Caption: Figure 8.
Panels (a) and (b) show the pixel position of the 5302.3 Å absorption-line minimum for slit 1, as a function of time, before and after spectral drift correction, respectively. Each data point is an average of ≈800 pixels along the spatial direction of the slit. The location of the absorption line in the slit can be seen in Figure 4.
