Fig. 2.
Left panel: ratio of the Gaia DR2 period to the primary period from the OGLE-III database for the LMC (blue) and SMC (red), respectively, as well as the corresponding histogram. Right panel: same, but using the OGLE-III period whose value is closest to the Gaia DR2 period. Above PGaia = 500 days, Gaia periods become uncertain owing to the limited time span of the Gaia DR2 data.
