GTO Programmes released

Guaranteed Time Observations (GTO) reward both individuals and teams of scientists who were selected to deliver of key hardware and software components, or technical and inter-disciplinary knowledge for JWST. The program provides a total of about 16% use of the observatory over the first 3 cycles of operation. See the section JWST Cycle 1 GTO Proposal Submission Policies for information on who is eligible to submit, observing time requirements (including overheads), data rights, restrictions on types of observations, and other policy information.

Each JWST GTO was required to submit a description of the proposed Cycle 1 science program, including specific targets and specific observations using the templates provided. Those observations specifications will be reviewed and revised, and are required to be finalized at a date at least two months before the Cycle 1 GO Call is released, at which time the specifications will be made public. At the same time, GTOs must develop detailed observing proposals, which are required to be submitted using the Astronomer’s Proposal Tool.  The Cycle 1 GTO proposal submission process, therefore, has three stages: (1) preparation of the Science Descriptions and Observation Specifications templates(2) finalizing reservations for publishing observing specifications, and finally (3) Astronomer’s Proposal Tool (APT) submissions for technical review and revisions. The section JWST Cycle 1 GTO Proposal Submission Process describes this process in full.

Initial JWST Cycle 1 GTO proposals and descriptions of observations were due on April 1, 2017. Finalized JWST Cycle 1 GTO observation descriptions and targets have been publicly released on June 15, 2017.
