Abstract. The Fourier transform of the (indefinite metric) Wightman two-point function tex2html_wrap_inline21 of a free massless scalar quantum field in two-dimensional spacetime has been reported inconsistently by various authors. We compute the correct one from the definition of the Fourier transform of tempered distributions.
