Potfile
=========

.. _potfile:

Use ``potfile`` keyword for file of potentials optimised together (following a scaling relationship).
---------------------------------------------------------------------------------------------------------

.. To use ``idPIE`` profiles, one must choose which ``dPIE`` profiles are considered to trace the X-ray signal.
.. The ``idPIE`` profiles use the same parameters as the ``dPIE`` profiles, but convert them into their corresponding hydrostatic ICM density, and computes the expected X-ray signal. The joint optimisation of selected profiles yields additional constraints.
.. In practice, ``dPIE`` profiles (id:``81``) are co-optimised with X-ray using ``idPIE`` profiles if keyword ``X-ray   2`` is added to the profile script.

For instance:

.. code-block:: console
