Doubly eclipsing binaries

It is nothing special, but I have discovered several doubly eclipsing binaries in MOA database. The figure below is one of them. It was achieved by first substracting the mean light curve with 200 bins from the one folded with P=0.409d and then redoing the period analysis to see if there is any hidden periodic variation.
