Light curves of ϕ Dra synthesised using the abundance maps of the individual elements separately, compared to the overall variability of the star (solid line) in several Gaussian passbands with the dispersion of 20 Å in the UV and the passbands U,Z, and S of the ten-colour photometric system. The light curves have been shifted vertically to better demonstrate the variability. We note the very different vertical scales of the two panels.
