Example notebook uses Omega_c = 0

[dkirkby]

I just noticed that the example notebook uses:

csm = {'omega_M': 0.3,
       'omega_B': 0.3,
       'omega_L': 0.7,
       'h': 0.7,
       'w': -1.0,
       'ns': 0.96,
       'sigma_8': 0.8}

leading to omega_C = omega_M - omega_B = 0. Is that intentional? The resulting linear matter power spectrum is quite weird:
