High resolution gamma-ray spectrum 50−100 days after the explosion around the 847 keV ⁵⁶Co line. Bins are 2 keV wide. The dashed line represents the DDT1p4 model. The solid line represents the emission of the 3Dbball model (the DDT1p4 plus a plume of 0.07 M_⊙ of ⁵⁶Ni out the equatorial plane). The dotted line represents the DDT1p4 model plus a plume of 0.06 M_⊙ of ⁵⁶Ni confined within the equatorial plane. All of them have been computed seventy five days after the explosion.
