Fig. 4
Top panel: the Pc1 pulsation power (thin black line) and the average variance of ROT (red line) on 22 February 2007. The thick black line highlights the pulsation power in correspondence to the time intervals characterized by an SNR greater than 3. Middle and bottom panels show respectively the 1-min phase σϕ and the amplitude S4 scintillation indexes on 22 February 2007 (different colors represent different satellites in the field of view of MZS; the black line is the 5-min average)
