Results of the mode identification by means of the pixel-by-pixel method for the three (out of four) frequencies detected in the spectra of HD 189631: f₁ (top left), f₂ (top right), and f₄ (bottom). The bottom-left and bottom-right panels stand for the (l,m) = (1,1) and (l,m) = (2, − 2) identifications, respectively. The solid and dashed lines stand for the observations (LSD spectra) and the (famias) model, respectively. The frequency values and their identifications are listed in Table 5.
