Attractor mass Mattractor as a function of redshift z accounting for the SNe Ia peculiar velocities in the combination of the Union2 and SNfactory datasets along with χ2 fitting via Eq. (20). The blue shaded area shows the uncertainty of the mass determined for a given attractor redshift. The green box shows the mass range as well as the approximate size of the SSC from Muñoz & Loeb (2008). The upper red dashed line shows the χ2 value for assuming no attractor while the lower one shows the χ2 value for a constant bulk flow.
