Caption: Figure 3.

Two Δχ ² maps of confidence contours in the (Π, ϕ _p) plane for (top) GRB 110301A and (bottom) GRB 110721A. The white dots are the best-fit parameters, and we calculate the Δχ ² values relative to this point. A color scale bar along the right side of the contour shows levels of Δχ ² values. The significances of the existence of linear polarization are 3.7σ for GRB 110301A and 3.3σ for GRB 110721A.
