Pairs of OGLE I-band light curves for both components of ten double Cepheids phased with the ephemeris from Table 2 for linear period change. Span of Y-axis is the same for each pair for easier comparison of pulsation amplitudes. In general, components A (with longer periods) have higher amplitudes, with the exception of OGLE-SMC-CEP-1526 (F + F) and OGLE-SMC-CEP-2699 (1O + F).
