Comparison of automated NN and manual normalisation for part of the spectrum of KIC 7023122. The NN normalisation and best fitting predicted spectrum are shown in blue and dark blue. The manually normalised spectrum and a synthetic spectrum computed for the corresponding parameters from Van Reeth et al. (2015) are plotted in orange and red. The lower panel shows the difference between the automated and manually normalised spectrum in grey, and the black line is the difference between the synthetic spectra. The most prominent element lines are indicated by dotted lines.
