.. py:class:: InterpolationChemistry(gases=None, filename=None, t_min=260)


   Bases: :py:obj:`pytmosph3r.chemistry.chemistry.Chemistry`

   Chemistry model interpolating Volume Mixing Ratios based on a datafile.
   See the `Abundances-TiO.dat <https://forge.oasu.u-bordeaux.fr/jleconte/pytmosph3r-public/-/tree/master/examples/parmentier/Abundances-TiO.dat>`_ for an example.
   VMRs should be in the logarithmic space.
   See :attr:`logp_grid` for details on the pressure format.

   :param gases: List of gases to consider for interpolation.
   :type gases: :obj:`list`
   :param filename: The path to the datafile.
   :type filename: str

   .. py:attribute:: t_grid

      Temperature grid (in K).

   .. py:attribute:: logp_grid

      Log(P) grid in Pa. For this, the pressure 'x' from the file is transformed via :math:`log_{10}(exp(x)))+2`.

   .. py:method:: compute_vmr(gas, mix_ratio)

      This function can be overridden to compute the volume mixing ratio of a gas :attr:`gas` using :attr:`mix_ratio`, initialized to an array with the :attr:`~pytmosph3r.Grid3D.shape` of the atmosphere.

      :param gas: Name of the gas
      :type gas: str
      :param mix_ratio: Array full of ones of shape :attr:`~pytmosph3r.Grid3D.shape`. The array is filled with the values in the atmosphere is the gas was already present, or else ones.
      :type mix_ratio: array, np.ndarray
