         If str, it needs to be 'x', 'y', 'z'.
         If tuple or list, it sorts the locations in two dimensions using lexsort.
         This approach is recommended since there is less ambiguity, by default ('x', 'y')

+    flip: bool, default: False
         If flip is False then the order is bottom first (starting from tip of the probe).
         If flip is True then the order is upper first.
