5 DD ERS Motivation and Goals In 2010, the JWST Advisory Committee first recommended the concept for the Early Release Science program:..to obtain images and spectra to demonstrate key modes to enable the community to understand the performance of JWST prior to the submission of the first postlaunch Cy 2 proposals that will be submitted just months after the end of commissioning. The JSTAC recommends that data be released both in raw form and with any initial calibrations as soon as possible; the key aspect is speed.

6 Ensure open access to representative datasets in support of Cy 2 proposal preparation. Engage broad cross-section of astronomical community in familiarizing themselves with JWST data and scientific capabilities. STScI Director Ken Sembach will allocate up to 500 hrs of DD time, and resources for up to 15 teams. A multi-disciplinary committee of experts will recommend a suite of proposals that fulfills the goals of the DD ERS; makes optimal use of the available time; and spans JWST s science themes. DD ERS Motivation and Goals

7 DD ERS Motivation and Goals The DD ERS program is guided by the following five principles: 1. Projects must be substantive science demonstration programs that utilize key instrument modes to provide representative scientific datasets of broad interest to researchers in major astrophysical subdisciplines. 2. Projects must design, create, and deliver science-enabling products to help the community understand JWST's capabilities. Initial products must be delivered by release of Cy 2 GO CfP (Sep 2019). Each project must define a core team to be responsible for timely delivery of products according to a proposed project management plan, with performance subject to periodic review.

8 DD ERS Motivation and Goals The DD ERS program is guided by the following five principles: 3. Early execution All observations schedulable within first 5 months of Cy 1 (expected Apr-Aug 2019), AND a substantive subset of observations schedulable within first 3 months. Target lists must be flexible to accommodate possible changes to scheduled start of science observations. 4. Data will have no proprietary time Both raw and pipeline-processed data will enter public domain immediately after processing and validation at STScI

9 DD ERS Motivation and Goals The DD ERS program is guided by the following five principles: 5. STScI recognizes and supports the benefits of having diverse and inclusive scientific teams involved in the formulation of ERS proposals. Programs with diverse representation of community members in a given sub-discipline helps ensure that the investigations will be of broad interest. Broad involvement facilitates the dissemination of JWST expertise through a more extensive network, and promotes more equitable participation in JWST scientific discovery.

10 Assess potential of proposal to achieve goals of DD ERS. DD ERS Evaluation Criteria 1. Extent to which project will improve community understanding of JWST science capabilities and guide subsequent JWST observations. 2. Effectiveness in providing deliverables which include quantitative, data-related measurements that will support development of Cy 2 proposals. 3. Extent to which science-enabling products will be developed to enrich overall scientific return of mission. 4. Credibility of management plan for achieving project goals in a timely manner, particularly development and delivery of scienceenabling products for community. 5. Overall scientific merit; significance to major astrophysical subdisciplines, and astronomy in general.

11 DD ERS: Differences from Standard GO Programs Short timescale delivery of science-enabling products. Science enabling products include, but are not limited to: higher-level data products (improved beyond standard products from STScI pipeline), software tools, documentation and other resources that demonstrate JWST's scientific capabilities or facilitate community science. Deliverables must include quantitative, data-related measurements to support Cy 2 proposal preparation, provided by the release of the Cy 2 CfP (Sept 2019). Science results by themselves are not science-enabling products. Proposers should take a broad, but realistic, view in determining level and types of products to be developed given relatively short timescales.

12 DD ERS: Differences from Standard GO Programs DD ERS Core Teams and Science Collaborators 1. PI, any Co-PIs, and Co-Is comprise the core team, with responsibility to develop and deliver science-enabling products, and carry out selected key aspects of the science investigations. 2. Science Collaborators contribute to formulation of proposed observations and articulation of full range of science applications May participate in core team activities, but no formal obligations to contribute to product development/delivery not funded through DD ERS but may propose for funding through Cy 1 Archival Research program

13 DD ERS: Differences from Standard GO Programs Funding provided for primary purpose of development, production, and delivery of science-enabling products. Required: deliverables that include quantitative, data-related measurements by Cy 2 GO CfP release (Sep 2019) Optional: products within 1 year of ERS obs delivered Cy 3 CfP release (Sep 2020). Funding provided for selected science enabled by DD ERS obs. All eligible researchers, including science collaborators and investigators on accepted DD ERS proposals, may propose for funding through Cy 1 Archival Research program to pursue studies beyond science funded by DD ERS. $5M anticipated; funding expected to begin Oct 2018 to allow teams to organize processing and analysis pipelines in preparation for receipt of data in Apr 2019.

14 DD ERS: Differences from Standard GO Programs Reviews and Community Briefings Continued funding contingent on satisfactory progress at each stage. APT Technical Review: Provide basic documentation on rationale underlying observing strategies. Released with final APT files in Dec Enables DD ERS programs to serve as templates for Cy 1 GO proposal planning. Readiness review: Before science observations, report on progress on preparatory activities; readiness to process and analyze JWST data. Examples: analyses of simulated dat asets to test post-pipeline data processing plans; customization and/or development of data analysis and/or software tools. Supports Jan 2019 briefing. Results review: Report successes and challenges encountered during analysis of early data. Status of initial products to be delivered by release of Cy 2 GO CP (Sept 2019). Supports Sep 2019 briefing.

15 In addition to immediate release of data, DD-ERS activities provide focal point for organization of GO user support, and dissemination of information on JWST performance and results. Accelerate dissemination of JWST know-how within 5-yr required, 10-yr anticpated lifetime.
