1. WP3000 : Padova ICC Contribution2007-2010 WP 3000.1 - Partecipazione all'ICC di PACS : fase di sviluppo WP 3000.2 - Partecipazione all'ICC di PACS : fase operativa WP 3000.3 - Partecipazione all'ICC di SPIRE : fase di sviluppo WP 3000.4 - Partecipazione all'ICC di SPIRE : fase operativa Mattia Vaccari (MV) Gabriele Mainetti (GM) & Giulia Rodighiero (GR) University of Padova – Department of Astronomy Padova ICC Contribution

2. PACS & SPIRE ICC Activities • Testing of PACS Instrument Simulator, Pipeline and AOTs • Definition of user requirements for Herschel Data Processing system • Development of Visualization Tools for SPIRE Interactive Analysis • Testing of Herschel Data Processing system at the astronomer level • Following the full Instrument and Data Processing Development Cycle Padova ICC Contribution

3. PACS Instrument Simulator 160 μm simulated image • Test del simulatore strumentale di PACS per l’identificazione di eventuali bachi del software, dal punto di vista di un utente. • 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. • 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. Padova ICC Contribution

4. PACS Pipeline • 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 Padova ICC Contribution

5. PACS AOTs • 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 • Individuazione delle migliori strategie osservative, validate dalle successive osservazioni PEP • 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 Padova ICC Contribution

6. 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) DetectorTimelineExplorerComponent Padova efforts focuesd on: DetectorTimelineExplorer TimelineSimplePlot DTMosaic 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 Padova ICC Contribution

9. 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 Padova ICC Contribution

10. 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 Padova ICC Contribution
