The Herschel/SPIRE Spectrometer Phase Correction Data Processing Tasks


Asymmetries in the recorded interferograms of Fourier Transform Spectrometers (FTS) can be caused by optical, electronic, and sampling effects. 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.
