deriv_dmp_osc_conv_cauchy

TRXASprefitpack.mathfun.deriv_dmp_osc_conv_cauchy(t: Union[float, ndarray], fwhm: float, k: float, T: float, phase: float) → Union[float, ndarray][source]

Compute derivative of convolution of damped oscillation and normalized cauchy distribution

Parameters

  • t – time

  • fwhm – full width at half maximum of cauchy distribution

  • k – damping constant (inverse of life time)

  • T – period of vibration

  • phase – phase factor

Returns

Gradient of Convolution of normalized cauchy distribution and damped oscillation \((\exp(-kt)cos(2\pi t/T+phase))\).
