Comparison between the periods reported in MQ14 (red) for the wide binaries in the Kepler mission and in RH20 (blue) from K2 and our adopted and vetted periods. Overplotted gray lines indicate the size of the offsets between our periods and theirs, as labeled. Open symbols denote stars with signs of binarity. The black ellipse marks double-dipping stars that were detected with their half-period. The two highlighted stars are the ones displayed in Figs. A.4 and A.5.
