Left uncorrected, these asymmetries will result in a spectrum with both real and imaginary components and thus a non-zero phase. One or more phase correction steps are applied in FTS data processing pipelines to correct for these effects. In this paper we describe the causes of non-zero phase particular to the Herschel/SPIRE FTS and present the two phase correction processing steps employed. The evolution of the phase correction algorithms is also described.STAMPAenConference paperhttp://aspbooks.org/custom/publications/paper/495-0343.html2015ASPC..495..343FFIS/05 - ASTRONOMIA E ASTROFISICA
