Accurate assessment of uncertainties in model fits of interferometric data. The bootstrap method

摘要

We propose a method to overcome the usual limitation of data reduction pipelines and of the Optical Interfer-ometry FITS format: the absence of correlated and non Gaussian errors. To do so, we use a bootstrap method that allows to sample the probability density function of the interferometric observables. We have applied the method to the accurate assessment of uncertainties on the stellar diameters of under-resolved stars.
