Fig. 6.
χ2 contour map for the vv7 model, considering the fit of HE 1439−1420 (the axis shows the two free parameters Mcut and MISM). The numbers associated with the contours give the χ2 values. The minimum χ2 is found for Mcut = 5.45 M⊙ and MISM = 1789 M⊙. These values produce the black pattern shown in the top left panel of Fig. 5.
