Frequency analysis of the Be star CoRoT 102656190 (star No 4) observed in the LRA1 run. Panel a: rectified light curve is shown; panel b: DFT of the rectified light curve is shown; panel c: DFT zoomed in on the second frequency group located at 1.7 c d⁻¹ is represented; panel d: DFT zoomed in on the third frequency group located at 3.5 c d⁻¹ is shown; and panel e: frequency spacings inside the third group are shown. The spacings in dashed green are comparable to f₁₇ and those in pink are comparable to f₁₄.
