Representation of the spot configurations of T-Cyg1-12664 in the (v,w) plane for the two epochs analyzed: the lower plot is for the Q6-1 epoch and the upper plot is for the Q6-2 epoch, which is displaced by an offset of 0.2 in the w axis. Both axes have units of relative radius. The stars are represented at orbital phase 0.020, just after the primary eclipse, and the secondary star is orbiting towards the right side.
