Quality comments
Off source observation in an unchopped range-scan pair; matched with the on-source observation 1342245796
The blue camera data was lost due to an instrument anomaly, but the red data processed normally
The offset between the central spaxel and the requested sky coordinates is 1.73" 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.
WARNING: The red channel was processed up to level 2.0, while the blue channel was processed up to level 0.0. See above quality summary for more information (if available)
