Rocky Worlds DDT: Teams
The final design and implementation of the Rocky Worlds DDT data program and the production of high-level data products is undertaken by the Core Implementation Team (CIT), working in conjunction with the Science Advisory Committee (SAC). The overall program is coordinated by the CIT Lead and their Deputy. The STScI Contributors will provide advice on high-level issues.

The CIT will be responsible for preparing the APT observing proposals, designing and implementing the observing schedule, processing the data, and preparing the high-level data products. CIT members are drawn from the STScI staff. The CIT Lead keeps the general community informed of progress, including regular briefings to the Space Telescope User Committee and the JWST User Committee, and public presentations at general meetings such as the AAS.

Scientific Advisory Committee (SAC) SAC
The SAC comprises of 12 research scientists from the community who are committed to providing scientific advice to the CIT on scientific aspects of the implementation process. SAC Members are expected to

  • Advise the CIT on scientific aspects of the implementation process, including the selection of appropriate targets, the observing strategy, feedback throughout the data gathering and analysis stages, and verification of high-level data products and analysis tools prior to their release to the general community.
  • Advise STScI on interactions with the broader community, particularly with regard to the equitable release of all data products and paths to achievement of the scientific objectives of the program.
  • Assist in the definition and science verification of high-level science products generated by the CIT.
