Example
~~~~~~~~~

::
    
    from PyAstronomy import modelSuite as ms
    import numpy as np
    import matplotlib.pylab as plt
    
    # Obtain an object of type VoigtAstroP ...
    v = ms.VoigtAstroP()
    # ... and set some parameters
    v["b"] = 87.7
    v["f"] = 0.5
    v["w0"] = 1214.0
    # Damping constant [cm]
    v["gamma"] = 2e-9
    
    # Generate wavelength axis ...
    wvl = np.linspace(1212., 1216., 200)
    # ... and evaluate model
    m = v.evaluate(wvl)
    
    # Plot result
    plt.plot(wvl, m, 'b.-')
    plt.show()



Example: Adding instrumental resolution

::
    
    from PyAstronomy import modelSuite as ms
    import numpy as np
    import matplotlib.pylab as plt
    
    # Obtain an object of type VoigtAstroP ...
    v = ms.VoigtAstroP()
    # ... and set some parameters
    v["b"] = 40.7
    v["f"] = 0.5
    v["w0"] = 1214.0
    # Damping constant [cm]
    v["gamma"] = 2e-9
    
    # Generate wavelength axis ...
    wvl = np.linspace(1212., 1216., 200)
    # ... and evaluate model
    m = v.evaluate(wvl)
    
    # Add (Gaussian) instrumental broadening with resolution 5000
    v["R"] = 5000
    mr = v.evaluate(wvl)
    
    # Plot result
    plt.plot(wvl, m, 'b.-', label="R = inf")
    plt.plot(wvl, mr, 'r.-', label="R = 5000")
    plt.legend()
    plt.show()
