AttributeError: 'CMD' object has no attribute 'filter1'

When running "Loading a pickled CMD file" in Colour Magnitude Diagrams.ipynb (for the JOSS review) and plotting the pickled_cmd object, like so:

pickled_cmd = unpickle(path='./data/cmds/cmd_bv_z020_bin_imf135_300')
plt.figure(figsize=(8,6))
myplot = pickled_cmd.plot(log_age=6.8)
myplot.set_xlabel('B-V', fontsize=14)
myplot.set_ylabel('V', fontsize=14)
myplot.set_xlim([-1,2.0])
myplot.set_ylim([2,-10])

I get the following error.

Thanks for spotting this!

The problem here was with the data I provided - the pickle files needed updating!

It should all work now.
