How can I fit lines to SPIRE spectra?

The Herschel Science Centre has produced a useful short videotutorial that shows you how to use a useful script in HIPE for SPIRE line fiiting (NB: it does not cover the fully interactive mode of line-fitting). You can find the short videotutorial here: https://www.youtube.com/watch?v=OYmJzolPF00 The short videotutorial covers the Instrumental Line Shape (ILS) of the SPIRE spectrometer, what preliminary processing of spectra is required, the inputs and outputs of the line-fitting script, and how the script works. Examples are shown of fitting lines to real SPIRE Fourier Transform Spectrometer data, how to inspect the residuals of the fit and to add missing lines in the fitted spectrum. Finally, it will introduce the Spectral Feature Finder Catalogue and how to use it as input for the line fitting script, running a spectrum fit with Spectral feature catalogue. | |
