R.; Rosolowsky, E. | Series: | ASTRONOMICAL SOCIETY OF THE PACIFIC CONFERENCE SERIES | Number: | 495 | First Page: | 343 | Abstract: | 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. | Conference Name: | Astronomical Data Analysis Software and Systems XXIV (ADASS XXIV) | Conference Place: | Calgary, Alberta, Canada | Conference Date: | 5-9 October 2015 | URI: | http://hdl.handle.net/20.500.12386/23936 | URL: | http://aspbooks.org/custom/publications/paper/495-0343.html | ISSN: | 1050-3390 | ISBN: | 9781583818749 | Bibcode ADS: | 2015ASPC..495..343F | Fulltext: | open |
