HPDPs have been identified by each instrument team, although it is likely that not all of them will be possible to prepared in certain cases. We indicate hereafter the HPDPs currently contemplated by each instruments, with some common delivery categories that will be considered or not.

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   Some level of manual reduction may be necessary, but are probably not many such observations  
Changed:

Off-centred 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. Pilar will check some of the 14.0 bulk results. Sample relevance analysis.

Off-centred point-source calibrated data For off-centred point-like 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. Pilar will check a subset of the 14.0 bulk results. Sample relevance analysis.  
 
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 Could be proposed for 14.1 SPG rather than HPDP 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). Conditional to NHSC bulk to be run.  
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. Sample relevance analysis.

Unchopped observations: manual processing to correct very bad transients Improved transient correction and background subtraction provided by processing the data manually Yes - level2/2.5 equivalent FITS files No Yes   Highly desirable, but depends on how many such observations there are and on progress on PACS-6462. Sample relevance analysis.  
Point-source calibrated data using the "POC" script products processed through the dedicated pointing offset correction script for bright point sources Yes - level2/2.5 equivalent FITS files No Yes   straightforward to do once the pipeline script has been fully validated and sources identified; validation is on-going (but not guaranteed to finish)

Point-source calibrated data using the "POC" script products processed through the dedicated pointing offset correction script for bright point sources Yes - level2/2.5 equivalent FITS files No Yes   Straightforward to do once the pipeline script has been fully validated and sources identified; validation is still on-going (postponed by the 14.0 AAT)  
 
Line list catalogue Spectral Feature catalogue No Yes - one file per obsid, and one concatenated file No   HPDP: dependent on available human resources, would be completely HSC to do, exploratory studies are being done with help of MSc students at ESAC and Leuven and we should know better early in 2016

Identifying background contamination; removing it? For ChopNod and Unchopped AOTs, looking at line (and continuum?) contamination in the off positions: primarily to make a quality comment, but if the number is manageable then also to correct for the contamination Yes - level2/2.5 equivalent FITS files No Yes   HPDP, for the quality comment part the ICC had agreed to do this, but for the subtraction part it would have to be done at HSC (note: unlikely to ever actually be completed, however, due to it being a difficult job)  
These should actually be SPG (14.1):

HPDP name Description Data Catalogue (tables) Images (PNGs, etc) Documentation (Readme, QSummary, etc) Notes Prototype delivery
Point-source calibrated data (pointed AOTs only) SPG products processed through the standard pipeline script and then creating point source spectra from them Yes, part of SPG obsContext No Yes   Note: is done on all pointed AOTs, regardless of whether the source is know to be a point or not. Done in 14.0  
Long range spectrometer flat-fielding - main Including flatfielding for range scans in the SPG Yes, entire obsContext No Yes   depends on validation in AAT 14. Done in 14.
