Statistical quality of Rheinland’s pole solutions shown in a sinusoidal projection of the sky in ecliptic coordinates. The color coding, and the scale bar on the right, indicates the value of ﹩{\chi }^{2}﹩ value normalized by the number of observations. The globally best-fit solution at ﹩(\lambda ,\beta )=(124^\circ ,-87^\circ )﹩ (full circle) has ﹩{\chi }^{2}=1.4﹩ (normalized by the 4021 data points). The solid line delimits solutions within the formal ﹩3\sigma ﹩ confidence zone and represents our region of admissible solutions (see the main text for details).
