>>> import numpy as np
>>> bins, width = 10, 5
>>> np.multiply(np.array(range(bins)) + width / 2.0, width).tolist()
[12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5, 52.5, 57.5]

Should be the following (the key being swapping the add and multiply operations):

>>> np.add(np.arange(bins) * width, width / 2.0).tolist()
[2.5, 7.5, 12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5]
