Statistical errors in equivalent widths -- A clarification

Instrumentation and Methods for Astrophysics 2019-05-23 v1

Abstract

In a recent mathematical approach, Netzel (2018) proposes a method for determining the statistical error of spectral line equivalent widths. Using various approximations, he derives a determination equation that differs significantly from earlier approaches by Vollmann \& Eversberg (2006) and Chalabaev \& Mailard (1983) and evaluates these works with his approach. Several points stand out, which have a not to be neglected influence on the evaluation of this approach.
