In practice, I don't use such graphs to compute tail probabilities because I can implement mathematical functions to return the tail probability for a given Chi Square value.
实际上，我不使用这些图来计算尾数概率，因为我可以实现数学函数来返回给定x平方分布值的尾数概率。

Recently published in the journal Icarus, this impact probability was calculated using two mathematical models to assess potential threats to Earth in the 22nd Century.
