def smaller(self, other):

Convert a co-ordinate to a bin index. The co-ordinate can be a single value, or a Python slice instance describing a range of values.

def __iter__(self):

Find bins in the denominator that are 0, and set them to 1. Presumably the corresponding bin in the numerator is also 0, so this has the effect of allowing the ratio array to be evaluated without error, returning zeros in those bins that have had no weight added to them.
