exp_conv_pvoigt¶
- TRXASprefitpack.mathfun.exp_conv_pvoigt(t: float | ndarray, fwhm: float, eta: float, k: float) float | ndarray[source]¶
Compute exponential function convolved with normalized pseudo voigt profile (i.e. linear combination of normalized gaussian and cauchy distribution)
\(\eta C(\mathrm{fwhm}, t) + (1-\eta)G(\mathrm{fwhm}, t)\)
- Parameters:
t – time
fwhm – full width at half maximum parameter for pseudo voigt irf
eta – mixing parameter
k – rate constant (inverse of life time)
- Returns:
Convolution of normalized pseudo voigt profile and exponential decay \((\exp(-kt))\).
