    The minimum and maximum of the range of the time variable implicitly
    defines the position of the first and last knot. The other knot positions
    are passed in knots. Conversely, the coeffs parameter records the height
    of the sline at all but the last two knot positions. The next to last knot
    coefficient is fixed to 1.0, thus fixing the overall scale of the
    acceptance function. The spline coefficient for the last knot is fixed by
    extrapolating linearly from the two knots before; this prevents
    statistical fluctuations at the low stats high lifetime end of the
    spectrum to curve the spline.
