 stream distribution function (DF). For this example, we will use the method
 implemented in [fardal15]_, incuded in ``gala`` as
 `~gala.dynamics.mockstream.FardalStreamDF`. Other methods of note are
-`~gala.dynamics.mockstream.StreaklineStreamDF` from [kuepper12]_, and

 the ``StreamDF`` classes take a few common arguments, such as ``lead`` and
 ``trail``, which are boolean arguments that control whether to generate both
 leading and trailing tails, or just one or the other. By default, both are set
