Fig. 3


Hemispherical asymmetry HN − HS in the Hubble rate H0 for each SN Ia fitter. The upper left plot is for MLCS2k2 (1.7), the upper right one is for MLCS2k2 (3.1), below are SALT (left) and SALT II (right). The deceleration parameter is fixed at the value q0 =  −0.601, which one obtains from WMAP (Larson et al. 2011). When the north pole lies in a region with a bluish colour, HN − HS is negative, the red spots denote the directions of positive large asymmetry HN − HS. The Hubble parameter has no anisotropy pointing towards white areas. All plots showing the asymmetry in the Hubble rate have the same scaling. The scale is given in Fig. 2. At the reddest and bluest spots, |HN − HS| = 3.4. We plot directions in galactic coordinates and Mollweide projection. The black line is the equator of the equatorial coordinate system.
