Abstract

Experimental line profiles can be altered by so-called spectral interference that appears due to different causes. One of the most commonly appearing sources of interference is random noise due to the detector used for measuring the spectra in the laboratory. In this work, the noise is studied using a simulation procedure. This study helps to pinpoint the changes that the noise produces in the parameters of the experimental profiles and, consequently, in the information provided by them.
