Features :
 
- 2D fitting with :class:`~fitroom.grid3x3_tool.Grid3x3`
- See the contribution of each slab in the line-of-sight with :class:`~fitroom.multislab_tool.MultiSlabPlot`
- Update an instrumental slit function interactively with :class:`~fitroom.slit_tool.SlitTool`
- Dynamic fitted parameters, linked to one-another with arbitrary functions with :class:`~fitroom.room.DynVar`. E.g:: 

    Tvib = 1.5 * Trot
    # Or :
    Trot_Plasma_CO2 = Trot_Plasma_CO

- Spectra computed on the fly, or tabulated, powered by :py:mod:`radis`.
- arbitrary line-of-sight and number of fitted parameters by fitting a combination of :py:func:`~radis.los.slabs.SerialSlabs` and :py:func:`~radis.los.slabs.MergeSlabs`
- Brute-force fitting with :class:`~fitroom.selection_tool.CaseSelector.precompute_residual`

.. note:: 

    Fitroom is better used as a tool to explore the effect of different fitting parameters, before 
    designing your own automatic fitting routines.
