-    :param number h_max: The maximum value that h can achieve, being h the shift between
-        images divided by the vector v (i.e the coordinates of the shift in base v).
-    :param number h_step: Spacing between the ``h`` tried. For any `` shift = h * v * idx``,

-        between two adjacent values of h.

+    :param int steps: Number of different tries of h.
     :param int nimages: The number of images to be used to find the best shift. It has to
         be smaller or equal as the length of the data. If it is smaller, the images used
         are chosen using `numpy.random.choice`, without replacement.
