Actually, get_uniform_copy cannot be any faster as it calls clone to make a copy and then fills it with the specified value:

    def get_uniform_copy(self, value=1.0):
        '''Initialises an instance of DataContainer based on the template'''
        y = self.clone() # SIRF uses `DiscretisedDensity.clone()` to make a copy of `self` data
        y.fill(value)
        return y
