The output of `sfs.plot2d.amplitude()`, `sfs.plot2d.level()` or any
other `matplotlib.cm.ScalarMappable`.
aspect : float, optional
Aspect ratio of the colorbar. Strictly speaking, since the
colorbar is vertical, it's actually the inverse of the aspect
ratio.
pad : float, optional
Space between image plot and colorbar, as a fraction of the
width of the colorbar.
.. note:: The *pad* argument of
:meth:`matplotlib.figure.Figure.colorbar` has a
slightly different meaning ("fraction of original
axes")!
\**kwargs
All further arguments are forwarded to
