Abstract
Real time deconvolution of photoacoustic waveforms using nonlinear least squares
methods has been successfully used to analyze the temporal profile of the heat released by
molecular excited states. In the present work we investigate the statistical distribution of the
errors by which the photoacoustic signal is affected. We introduce the X2 test to judge the
goodness of fitting and obtain the confidence intervals of the recovered parameters.
