Replace np.concatenate by iterable unpacking when the arrays are short
(so performance doesn't matter) and legibility is improved, or by
np.roll(), or by np.append.

How does this work?n is an array still, buthour_steps is a list now, and I can't index a list with an array.

dv is a scalar (this is called by select_step, where it is immediately preceded byif dv > 1 / threshold_factor -- semantically, it is the distance between the axes bounds) so n is a scalar as well and the indexing is fine.

I guesstechnically it is an API break in that select_step_degreecould have been called directly by someone passing dv as an array, but I don't think this is a real issue (and is clearly not how select_step_degree was designed to do).
