Quality comments
It seems that the observer erroneously swap the ON and OFF positions coordinates of this observation in HSPOT. It requires a manual reprocessing and the final products will be provided as Highly Processed Data Products (HPDP) through the Herschel Science Archive
The offset between the central spaxel and the requested sky coordinates is 1.87" in the dispersion direction.
If the target is point-like and is offset from the centre of a spaxel in the dispersion direction, the spectral line
profiles will develop a skew. This skewed Gaussian profile becomes more extreme as the offset increases.
Be aware that this can be confused with real velocity structure.
This will affect spectra from a single spaxel of a rebinned cube (products with filenames "..hps3dr[r|b].."),
and combined spaxel-spectra, i.e. added rebinned cube spaxels, or single spaxels from an interpolated or projected cube
(products with filenames "..hps3di[r|b].." or "..hps3dp[r|b].."). See the "PACS Handbook" for more information.
