Pipeline processing bright sources Very bright sources ought to be reduced with a difference pipeline script (to account for non-linearity/self-curing) Yes - level2/2.5 equivalent FITS files at a minimum, or entire obsContext if done via SPG No Yes To be proposed for 14.1 SPG rather than provide as an HPDP Some level of manual reduction may be necessary, but are probably not many such observations

Point-source calibrated data For off-centred point sources: SPG products processed through the standard pipeline script with non-standard extraction of final PS spectrum Yes - level2/2.5 equivalent FITS files No Yes   A useful possibility, feasibility will be more clear once QC work (http://herschel.esac.esa.int/twiki/bin/view/Pacs/QualityCommentsSpec) on off-centred observations and identification of likely centred point sources has been done

Long range spectrometer flat-fielding - potential Correcting the few cases of bad flatfielding Yes - level2/2.5 equivalent FITS files No Yes   may be unnecessary if the new range scan flatfielding works well  
Unchopped observations: pipeline processing with new response drifts correction Improved transient correction and background subtraction as provided by the new NHSC pipeline scripts Yes - level2/2.5 equivalent FITS files, or entire obsContext if done via SPG No Yes To be proposed for 14.1 SPG rather than provide as HPSP Highly desirable, but requires a fuller validation of this script first (if the script does not provide improved results, neither SPG nor HPDP can be created here)  
Unchopped observations: subtracting the baseline If the continuum in these AOTs cannot be improved (wrt absolute level and shape, less wrt SNR) then instead subtract the baseline Yes - level2/2.5 equivalent FITS files: baseline subtracted cubes/spectra and cubes of the baseline that was subtracted No Yes   Desirable, necessary if the new transients correction pipeline does not becomes SPG in 14.1

Semi-Extended calibration correction SECT correction for semi-compact sources Yes - level2 equivalent FITS files No Yes - postcards Yes  
Extended background correction Extended background correction for point sources Yes - level2 equivalent FITS files No Yes - postcards Yes  
Anomalous data correction Isolated cases of failed processing due to some on-board anomaly Yes - level2 equivalent FITS files No Yes - postcards Yes
