... A multi-dimensional binary search tree, k-d tree, is proposed to support range queries in multi-key data sets. The algorithm can been used to solve a near neighbors problem for objects in a 19 million entries star catalog, and can be used to locate radio sources in cluster candidates for the X-ray/SZ Hubble constant measurement technique. ... The choices for the problem at hand were narrowed down to two : a Multidimensional k-ary Search Tree (MKST) and a k-dimensional (k-d) tree. ...
