  2. Herschel SD Phase Objectives  Demonstrate to the astronomical community what the actual scientific capabilities of the observatory are (what Herschel can/can’t do)  Show what we can learn scientifically from observations performed successfully from a technical point of view  Demonstrate that the science objectives can be addressed with the actual performance of Herschel  Produce material for PR/communications purposes (but PV observations will also be used for PR) Science Demonstration Phase Matt Griffin 2

  3. Implementation  After PV but before Routine Phase Assumes the relevant AOTs are validated PV phase To be performed with “routine phase” HSpot-generated AORs  Wide range of types of observations Duration: Nominal baseline = two weeks per instrument Major workshop at end of SD Phase- Presentations of lessons learned from PV and SD phases - Changes to manuals, AOTs etc. based on in-flight experience - Updating of the science programme - Easy: modify KP AORs in the database and release for scheduling - Difficult: any significant changes (e.g., programmes becoming impossible or unacceptably compromised: - HOTAC has to adjudicate Any SD observations may be used for PR Science Demonstration Phase Matt Griffin 3

  4. Process for Selection of SD Observations • Göran Pilbratt to produce a formal note covering rules and procedures (end October)- Will specify format and necessary (brief) content of proposals • GT holders to submit proposed observations (end Nov.) • Herschel Science Team will review inputs (January meeting) • OT holders asked to provide suggestions for areas not adequately covered (~ Jan/Feb?) • Compilation of suggestions for special observations (Feb/Mar?) • Further iteration/consolidation/final agreement (Mar/Apr?) Science Demonstration Phase Matt Griffin 4

  5. Guidelines for Selection • Order of selection - First choice: Volunteered small parts of approved GT KPs - Second choice: Volunteered small parts of approved OT KPs - Third choice: New observations if everything is not properly covered by 1 and 2. No source overlap with approved KPs; data publicly available immediately. • Two cases for KP observations: 1. Full release of ‘raw/quantitative’ data - Time is reimbursed and can be used according to the “robustness” statements in the original proposal - Not an obligation, but preferred by ESA 2. Release of “non-quantifiable” data - No reimbursement; data rights remain with the data owner for the duration of the normal proprietary time - Not preferred by ESA Science Demonstration Phase Matt Griffin 5

  6. Proposed SPIRE Approach • Our objectives:1. Demonstrate and advertise as effectively as possible the actual scientific capabilities of SPIRE, 2. Make sure that all KPs that use SPIRE can be properly optimised before routine observations begin3. Protect our GT science from predators (but not at the expense of 1 and 2).  Photometer and Parallel Mode- Extensively used in KPs – therefore important to demonstrate •  Spectrometer- Under-used in KPs – therefore important to demonstrate Science Demonstration Phase Matt Griffin 6

  7. This Meeting  Review of ideas collected so far (inputs from SAG Coordinators) - Presentations by Bruce and Jean-Paul Additional discussion - Our policies/approach concerning data release - Areas where - we already know that OT observations will be needed - we think special observations will be needed - The need for coordination with PACS - Parallel mode demonstration - Common sources to show capabilities of PACS + SPIRE combination Science Demonstration Phase Matt Griffin 7

  8. Suggested Next Steps  Update of SPIRE SD Phase Plan, to incorporate - Our proposed GT observations and corresponding justification - To be compiled by small group based on SAG inputs (Matt, Laurent, SAG Coordinators) - Based on what is optimum to show SPIRE capabilities- Our ideas for OT observations (but all OT KP holders will be given a chance to offer observations) - Our ideas for special observations Iteration of the plan via e-mail/telecons - SAG Coordinators/Co-Is Agreement and submission of the SD Phase Plan by end Nov. Further iteration after Herschel Science Team review Science Demonstration Phase Matt Griffin 8
