Dynamic diagram of stellar activity pattern (DDSAP) for the star KIC 9009514 with an effective temperature of T = 4569 (according to MAST) and P_rot = 1.211 days (according to Nielsen et al. 2013), which shows a typical activity cycle. The accompanying upper plot presents the varying activity index σ_F, as a sequence of the standard deviations of ΔF_n, calculated for each given one-rotation interval. The vertical black bands and strips as well as the black dots in the DDSAP are caused by gaps in photometric data.
