HITEMP
------

.. _step-1-species-properties-1:

Step 1, Species Properties
~~~~~~~~~~~~~~~~~~~~~~~~~~

For HITEMP, the same ``Hitran_species.dat`` is needed as for HITRAN. See
:ref:`HITRAN_step_1`.

.. _step-2-download-the-files-1:

Step 2, Download the files
~~~~~~~~~~~~~~~~~~~~~~~~~~

The line list files must be downloaded manually from
``https://hitran.org/hitemp/``. The same partition function files are
needed as for HITRAN, see
:ref:`HITRAN_step_2`.

.. _step-3-create-<-species->.param-file-and-binary-files-1:

Step 3, create ``< species >.param`` file and the binary files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All necessary files can be created with:

::

   ./hitran -M < molecule ID > -ISO < isotopologue ID > -in < line list name >

The ``<molecule ID>`` is the two digit molecule number, e.g. ``01`` for
H2O. The ``<isotopologue ID>`` is the hitran internal isotopologue
identifier, e.g. ``1`` for 1H2-16O. The ``<line list name>`` is the name
that was given in the download section, e.g. ``HITEMP2010``.

.. _step-4-data-path-2:

Step 4, data path
~~~~~~~~~~~~~~~~~

Include the path of the directory, which contains the obtained binary
files, the ``*.txt`` partition function files and the ``*.param`` file to
the HELIOS-K ``param.dat`` file under ``pathToData``.

	How to cite HITEMP

	When using the HITEMP database, please cite the appropriate HITEMP article (e.g., [1]) as well as the original sources of data. To assist the user, each line transition has reference codes that are provided for each parameter and are consistent with those in HITRAN for the same molecule. We hope that you will find HITEMP helpful in your research.
