Quality comments

This observation was performed at 'warm' attitude conditions (Star Tracker 2 temperature > -15 C), leading to astrometry shifts induced by thermoelastic drifts which in the case of this observation are estimated to result in an offset of 3.3" in Right Ascension and -0.7" in Declination.
The offset between the central spaxel and the requested sky coordinates is  1.72" 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.
