  • Use finite differences to estimate derivative rather than splines
    (which are conceptually much more complicated).
  • Include a "constant error" case, which shows that the band does have
    constant width in that case.
  • Force the axes aspect to 1 (so that constant width actually appears
    constant).
  • Use np.full() to set up the codes array.
