JLA_example.ipynb does not produce the output shown

[Andromedanita]

The magnitude histogram and the redshift distribution plot shown in JLA_example.ipynb in line 18 and 19 are different from the ones shown in example notebook when I run it on my computer (Mac OS 10.9.5) with sncosmo version 1.4.0

The histogram I get is here, and the histogram shown in the example notebook is here.

note: This includes prior on redshift.
