It is written, $\chi_{1-\alpha,h}^2$ is the $\alpha$-quantile of the chi-squared distribution with $h$ degrees of freedom.

Does $\chi_{1-\alpha,h}^2$ mean:

1. The area below the graph of $\chi^2(h)$ from $\chi_{1-\alpha,h}^2$ to $\infty$ is $\alpha$, or
2. The area below the graph of $\chi^2(h)$ from $\chi_{1-\alpha,h}^2$ to $\infty$ is $1-\alpha$?
