Fig. A.1

Doppler images of XX Tri for the observing season 2007/08. Each DI is shown in four spherical projections separated by 90°. The rotational shift between consecutive images is corrected, i.e., the stellar orientation remains the same from map to map and from season to season. The time difference between each Doppler image is indicated in units of rotational phase φ.
