In this article, the legend for Fig. 1 was incorrect. The term “horizontal” was erroneously used instead of “vertical” to describe the quantiles. The legend should read “vertical” throughout (see revised legend). The error makes the figure difficult to interpret. We apologize for this mistake.

The original article has been corrected.
