SPIRE Spectrometer Background Subtracted Sparse Mode Spectra
SPIRE Fourier Transform Spectrometer sparse mode observations cover all types of sources: point-like, extended and semi-extended. The targets, as proposed by the observers, may be embedded in a foreground or background emission. The standard pipeline processed data products were carefully analysed and those that were considered centred on point sources embedded in a background were further processed, using the smoothed spectra of the off-axis detectors to remove the fore/background contamination from the central ones. With some caveats the background subtracted spectra are considered higher quality science products than the default ones from the standard pipeline.
