Slit-reconstructed maps of the line-core intensity (top) and the LOS velocity (bottom) for the spectral lines He I (left), Si I (middle), and Ca I (right) observed with GRIS at 09:02 UT on 2016 September 24. The contours are the same as shown in Fig. 7. Simple line-fitting did not deliver proper fits for the Ca I line profiles in the umbra, which appear as conspicuous white patches in the respective velocity map.
