Position of the system and the Cepheid on the color–magnitude diagram for type II Cepheids in the LMC. After the subtraction of the component light the Cepheid moves to the zone occupied by typical W Virginis stars. It is possible that all the outliers on this plot are members of binary systems with bright companions of very different color.
