The main movie 1 shows four different projection styles simultaneously. In the top row, from left to right, equidistant Mercator projection, true-area Aitoff projection, and a pole-on view. The bottom row is a phase-resolved orthographic projection for four specific rotational phases (ϕ = 0.00, 0.25, 0.50, and 0.75) and an inclination of 60°. Stellar surface longitude and latitude are always indicated in steps of 30°. Time is counted in stellar rotations, in civil date, and in HJD. The real-time coverage is 237 stellar rotations from August 2006 to February 2022 (about 16 years) or 5670 days. Movie duration is three minutes and nine seconds. Surface color is always coded in terms of temperature as defined in the color bar. The four projection styles can also be viewed from individual files. Movie format is, in all cases, mp4, and all movies cover the entire 16 years of observations.
