notes
---------

The discretization in time steps is as follows:

10 steps for :math:`[0.,\mathrm{1.D}-3]` or :math:`\Delta t={\mathrm{1.D}}^{-4}`

9 steps for :math:`[\mathrm{1.D}-3,\mathrm{1.D}-2]` or :math:`\Delta t={\mathrm{1.D}}^{-3}`

9 steps for :math:`[\mathrm{1.D}-2,\mathrm{1.D}-1]` or :math:`\Delta t={\mathrm{1.D}}^{-2}`

9 steps for :math:`[\mathrm{1.D}-1,\mathrm{1.D0}]` or :math:`\Delta t={\mathrm{1.D}}^{-1}`

9 steps for :math:`[\mathrm{1.D0},\mathrm{10.D0}]` or :math:`\Delta t=1.0`

3 steps for :math:`[\mathrm{10.D0},\mathrm{13.D0}]` or :math:`\Delta t=1.0`
