We indicate hereafter the HPDPs currently contemplated by each instruments, with some common delivery categories that will be considered or not. |

| 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 |

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) |

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) |

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): |

Yes - level2/2.5 equivalent FITS files |

HPDP, for the quality comment part (just identifying that there is contamination) the ICC had agreed to do this (although work is not yet on-going), but for the subtraction part it would have to be done at HSC, if deemed necessary |

| Point-source calibrated data (pointed AOTs only) |

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. |
