Quality comments
On source observation in an unchopped range-scan pair; matched with the off-source observation 1342262989
The offset between the central spaxel and the requested sky coordinates is 1.85" 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.
