Description: # Non-uniform Temperature Fitting (NTfit)

        Nonuniform-temperature fitting code, to extract spatial temperature variations along a laser path. For high-temperature gas diagnostics.
        
        In support of the 2-part paper series N.A. Malarich and G.B. Rieker, "Resolving nonuniform temperature distributions with single-beam absorption spectroscopy"
        
        Nonuniform-temperature fitting is a two-step process. 
        The Python package ntfit has sub-packages for each step.
        1) `ntfit.spectrafit`: Extract linestrengths from broadband spectrum with E"-binning.
        2) `ntfit.tdist`: Fit temperature distribution from linestrength fit in (1) with Tikhonov regularization.
        
        For help running the fits, check out `examples/Example_td.py`, or the associated .ipynb (Jupyter Notebook) file.
        
        
        ## Package requirements
        Your computer must already have the following Python packages:
        ```
        python3.x
        numpy
        matplotlib
        scipy
        ```
        NTfit also includes [HAPI](https://github.com/hitranonline/hapi), available under MIT license. 
        NTfit changed HAPI version 1.1.0.9.6 lineshape equations (power-law temperature dependence) from original HAPI to improve high-temperature acuracy.
        See `ntfit/hapi/hapi_combustion.py` docstring for details.
        Partition functions are calculated using TIPS2017.

        # Change Log
        
        ## [2.1] - 2022-09-23
        ### Changed
        - ntfit now a separate sub-package, compatible with pip install
        - `hapi` sub-package has separate file for Q(T) tables
        - Removed uniform_fit example, as lookup table is much more efficient way to fit temperature
        - Tikhonov regularization module now `ntfit.tdist`
        - E"-bin spectral-fitting now `ntfit.spectrafit`
        
        ## [2.0] - 2021-03-01
        ### Added
        - E"-bin spectral fitting package with hapi
