BVr band light curves for Model r48_d5.0_Z (angle-averaged as well as a faint and bright viewing angle) compared with SN 2019muj (Barna et al. 2021). Model r48_d5.0_Z produces the best agreement in terms of its light curve and spectra compared to SN 2019muj. The model light curves are plotted relative to the explosion time predicted by our simulations, whereas the band light curves of SN 2019muj have all been shifted 2 days earlier than the explosion epoch estimated by Barna et al. (2021) such that SN 2019muj matches the brightest viewing angle shown (blue) for the model at B peak. The viewing angle looking along the axis that the ignition spark is placed is θ = 90° ϕ = 0° meaning the fainter viewing angle shown (red) is looking almost along this axis whereas the brighter viewing angle is looking along the axis directly opposite.
