Typically, models of type 1a supernovae have masses ranging around the mass suggested by Chandrasekhar many moons ago. 4500 examined simulations suggest that smaller masses fit the observations best. See:https://arxiv.org/abs/1801.00789

Well...there goes the neighborhood, so to speak. I guess a three magnitude range of events is better than a four or five. If you factoring in the quirky and elusive (reddening, lensing, selection and/or evolutionary) effects obvious in the cosmic sample, there is a lot of room for error in the Supernova Hubble factor(s).

Why 4500 simulations? Why that number?
