Another issue with distribution is that there is large under-representation of DA and over-representation of DC white dwarfs - I was wrong and it looks like those large islands I mentioned have to be procedurally generated (there are too many of them for manual introduction I think). Perhaps the main issue is that they have forgotten or they haven't enough time to introduce almost all known white dwarfs (over 10 thousand). Nice thing is my ticked has already been answeredThe distribution is certainly wonky as there's a few near Sol then none far out until you hit the galactic center then if you look above/below central plane you see ~50% white dwarfs with others being neutron stars and black holes.
