Reconstructed maps from the spectra and fitting parameters. (a)–(b) Intensity maps of the Si I and Hα line center. The arrow points to disk center. The red plus symbols denote positions whose line profiles are shown in Fig. 9. (c)–(d) Line-center depth maps of the Si I and Fe I line. (e)–(f) Doppler maps of the Si I and Fe I line. (g)–(h) Line-width maps of the Si I and Fe I line.
