The `TH1K` class is deprecated and will be removed in 6.40. It did not implement the `TH1` interface consistently, and limited the usability of the k-neighbors method it implemented by closely coupling the algorithm with the histogram class. Instead, one should use the new `TMath::KNNDensity` function that implements the same mathematical logic.
