PACS Instrument Simulator
160 μm simulated image
A) Test del simulatore strumentale di PACS per
l’identificazione di eventuali bachi del
software, dal punto di vista di un utente.
B)
Sono stati individuati e riportati al working
group vari problemi negli output del
simulatore. Le frequenti telecon hanno
permesso di riportare in modo continuativo le
problematiche individuate e di riportarle agli
sviluppatori per individuare una soluzione.
C)
Le expertise acquisite dal team italiano (GR)
nell’utilizzo del software hanno permesso di
utilizzarlo come strumento nella preparazione
delle osservazioni di Guaranteed e Open
Time, creando mappe simulate con le diverse
configurazioni richieste dai diversi proposal.

PACS Pipeline
A) Utilizzo del simulatore per testare alcuni moduli della pipeline del
fotometro di PACS
B) - Generazione di timeline simulate corrispondenti alle osservazioni del
GT PACS
- Esecuzione e test della pipeline sulle timeline simulate
- Applicazione dei moduli High-Pass Filtering e PhotProject per produrre
mappe del cielo
- Utilizzo di dati SOVT2 come input alla pipeline
- Partecipazione ai meeting tecnici del GT per la validazione dei vari test
della pipeline
C) Questi impegni hanno contribuito ad un’estesa validazione sia del
simulatore dello strumento PACS che al software di Data Processing dai
raw data al Map Making

PACS AOTs
A) Test degli Astronomical Observing Templates (i.e. Observing Modes)
per ottimizzare l’esecuzione delle osservazioni per le survey
extragalattiche sia nei programmi di Guaranteed Time che di Open Time
B) Individuazione delle migliori strategie osservative, validate dalle
successive osservazioni PEP
C) Particolare contributo italiano alla pianificazione del campo COSMOS
Screenshot detailing the coverage of the
COSMOS field as observed by the PEP
Guaranteed Time Key Program
A scan mapping strategy with perpendicular
“cross-linked” scans was adopted to
homogeneously cover the field and remove
correlated noise during data reduction

Visualization Tools for SPIRE Interactive Analysis
Aim of the work : developing Visualization Tools for Interactive Analysis of
SPIRE raw and reduced data (from level 0 to level 2).
• Understand the goodness of an observation
• Understand any problems of the detectors
• Use/manage/visualize the data for further processing
Two ways : script (Jython) or Graphical User Interface (GUI)
Padova efforts focuesd on:
1. DetectorTimelineExplorer
2. TimelineSimplePlot
3. DTMosaic
DetectorTimelineExplorerComponent
Level 0.5-1 product
Detector Timelines
• Intuitive view of detector arrays
• Powerful plotting tools
• No Jython involved
TimelineSimplePlot
DTMosaic
•DetectorTimelineExplorer is the default viewer for the SPIRE Detector Timeline product within
HIPE. In HIPE from version 1 .0.
•TimelineSimplePlot in HIPE from version 4.0.
•DTMosaic in HIPE from version 5.0
•GM is the owner of the spire_ia_gui package

Herschel DP CCB & Users Group Activities
 MV represented SPIRE within the Herschel Data Processing (DP) Configuration
Control Board (CCB) and Users Group (UG) and chaired the SPIRE DP UG
– Assembling and coordinating DP feedback from SPIRE consortium members
– Participating into DP CCB telecons and DP UG meetings
– Supervising (Mentoring) DP development related to a number of WPs
 Development of Herschel DP has benefited from the exposure to a larger pool of
dedicated users, stimulating ICC members to take action on issues raised by KPs
 The Herschel DP UG has recently spawned a number of DP Interest Groups (IGs),
including the “PACS and SPIRE Large Maps & Source Extraction” IG coordinated
by Mattia Vaccari as mentor for the related DP WPs
 Following SDP papers and the AO for OT, the Herschel DP UG will include new
members from the IGs, supporting the newly established Herschel Users Group

Conclusion : Padova ICC Contribution
 GM, GR, MV have represented Padova within the PACS and SPIRE ICCs
throughout the 2007-2010 pre-to-post launch timeframe
 They have provided a substantial contribution to:
–
–
–
–
pre-launch development and testing of the Herschel general DP and SPG system
post-launch improvements to general DP and SPG following community feedback
execution of PACS and SPIRE SPG pipelines as part of the HerMES and PEP GT KPs
involvement by the general astronomical community
 Their work has ensured that Padova is recognized as an important player within
the largest PACS and SPIRE GT KPs, thus continuing its long-time involvement in
IRAS, ISO, Spitzer and now Herschel extragalactic survey science
 They are now in a position to provide expert knowledge about the instruments and
data processing system but also to carry out ground-breaking science with them
 They have greatly contributed to providing the ICCs with early astronomers
feedback on one hand and to popularizing Herschel and its data processing system
within the extragalactic astronomical community at large on the other
