Pulsation properties of the 148 δ Sct EB candidates identified in this work. Top: pulsation periods of the highest peaks of the oscillation spectra Ppuls as a function of orbital periods Porb. Bottom and left x- and y-axes are in the same units as in Liakos & Niarchos (2017). As in this latter paper, the vertical line indicates a 13-day orbital period, while the horizontal lines indicate pulsation frequencies of 3 and 80 cycles per day (c/d), respectively. Top and right x- and y-axes are the same in days for Porb and in frequency for pulsations. Bottom: representation of the height of the highest peak per δ Sct spectrum as a function of Porb. In both panels the color scale indicates the number of systems per square, to help the reader look for trends, such as possible clustering. The two vertical dotted lines indicate orbital periods from 0.6 to 3.2 days.
