Fig. 4

Comparison between ARMA gap-filling (red) and the linear interpolation (blue) for the light curve of the Be star HD 51193 observed by CoRoT. In the inset we show a short segment of 1.44 h of duration. Note that the size of gaps is about 0.014 d, which is two orders of magnitude smaller than the pulsation period of the star (~days).
