Figure 1: Light curves of Abell 43 shown for the three long NOT runs. The solid lines are synthetic light curves constructed from the parameters listed in Table 2, and shifted downward by 0.005 units for clarity. |

Figure 2: Pulsation spectrum of the light curve of the NOT run from the 2nd of July, 2005. The insert is a blow up of the low frequency region, that shows the evident lack of excited frequencies above 0.5 mHz. |

Figure 3: We show the DFT computed from the combined light curve of five runs used in the analysis. The top curve shows the window function. The second curve shows the DFT of the light curve. The third curve shows the DFT after subtracting out the two highest amplitude peaks. The lower four curves show the DFT after subtracting three, four, five, and six frequencies respectively. |
