Stokes q vs. u parameters for the GRB sample (excluding GRB 120308A). The red point (with error bars) indicates the GRB, and the black points (without error bars) are the other objects in the same frame. The q and u values have been corrected for instrumental polarization using the measured instrumental zero-points. The data have not been corrected for instrumental depolarization.
