        gamma	69 +/- 3

    • rhobar-etabar plane using angles only: http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/angles_postEPS11.eps

      • parameter	fit output
        rhobar	0.129 +/- 0.027
        etabar	0.340 +/- 0.016

    • rhobar-etabar plane not using angles (sides and epsk): http://pprc.qmul.ac.uk/~bona/utfit/postEPS11/sides_postEPS11.eps

      • parameter	fit output
        rhobar	0.155 +/- 0.038
        etabar	0.404 +/- 0.039

    • compatibility plots: .to “measure” the agreement of a single measurement with the indirect determination from the fit using all the other inputs:
      • Color code: agreement between the predicted values and the measurements at better than 1, 2, ...nsigma.//
        • The cross has the coordinates (x,y)=(central value, error) of the direct measurement
