Density maps of the Monte Carlo simulations of the inclination vs. eccentricity (upper panel) and the inclination vs. argument of periastron (lower panel) for the non-beaming case. The grey scale depicts the χ²values mapped across the grid. The colour bar depicts the grey scale pertaining to the different values of χ². The contours (from inner to outer) denote the 1σ (dotted white line), 2σ (dashed blue line) and 3σ (solid green line) confidence intervals. The uncertainties for the inclination, argument of periastron and eccentricity were determined using the 1σ confidence contours displayed.
