JWST Example Science Programs
Example science programs, available to prospective JWST proposers, provide a walk-through of all the elements in creating a JWST observing program, from posing a question, to identifying instrument-specific modes optimized for science goals, to using proposal preparation tools needed to create a valid proposal.
All example science programs presented below were constructed prior to launch.
A few examples have been updated to include content based on Cycle 3 versions of ETC and APT but most other examples remain unchanged. Therefore, details contained in these examples (such as exposure parameter specifications or achieved S/N values, etc.) may be different than those produced by the updated ETC and APT tools available post-launch. However, they are still judged to provide good guidance for the process of going from a science use case to a finished proposal, by way of running the ETC and preparing an APT file for submission.
Due to ongoing development of ETC and APT, you may see minor differences in the GUI appearance when compared to screen shots in the example articles. Also, the detailed results produced by the current ETC will be different from those described in these examples because on-orbit sensitivities have been updated from pre-launch expectations. Hence, while details may be different, these examples are still deemed useful for training purposes.
The example science programs listed in Table 1 are actual worked proposal examples for a number of JWST instruments, modes, and combinations of instruments. They are written as step-by-step guides to follow along, and will serve as a useful reference when crafting your own proposals.
These examples each include a description of the program, along with step-by-step guides to using Exposure Time Calculator (ETC) workbooks and Astronomers Proposal Tool (APT) files. Descriptions provide background on the science goals of each program and also walk through some of the technical decision-making steps in crafting realistic programs. ETC workbooks and filled-out APT files for the examples are available within each of those tools from a pull-down menu (see below).
Note the program reference numbers in the first column; they provides a numerical ID that ties together the description, ETC, and APT components of an example, as well as other relevant JDox articles.
With the availability of public domain APT files and actual JWST data in the MAST archive, we expect many proposers may use these materials as examples going forward. However, users may still find the descriptive materials provided in these examples a useful supplement for understanding the process of moving from a scientific use case to a finished proposal.

Each of the example science programs linked above also links to two step-by-step guide articles, one for creating the ETC information and the other for creating a valid APT file. The actual example ETC workbooks and APT files for each program are available from within each tool, as described below.
