Due to an instrument anomaly the grating movement was inhibited during the first repetition of a range, for each raster position. The data have been pipeline processed correctly, but the SNR will be lower than expected due to the fewer repeats on the spectral range than requested. Off source observation in an unchopped range-scan pair; matched with the on-source observation 1342227759 The offset between the central spaxel and the requested sky coordinates is 1.64" 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.
