Updated 3/27/2018: The JWST Cycle 1 GO/AR deadline has been delayed. See the March 27 news article for more information.
Cycle 1 General Observer proposals are due April 6, 2018. While it may seem like there is plenty of time to prepare your proposals, April will be here in no time. Some of the tools you need to use require a certain amount of effort to learn their use, and you shouldn’t wait until the last minute! In addition to familiarizing yourself with the technical requirements, you should review the Cycle 1 Call for Proposals, including the science policies and proposal checklist. We want to ensure you have all of the information you need and share some tips to help with your proposal planning.
As a reminder, JWST uses a “single-stream” approach to proposals. This means that all information about the proposed science and observations are provided up front at the time of submission. This is similar to the process used at other space observatories (such as Spitzer and Chandra), but is different from the two-step proposal process familiar to HST users.
You will want to learn to use the JWST Exposure Time Calculator (ETC) to verify the feasibility of your JWST proposed observations as well as to determine the exposure specifications needed for your proposal. The ETC is a powerful and flexible new tool, but involves a learning curve in order to use it effectively.
You will also use the Astronomer’s Proposal Tool (APT) to submit your observing requirements using a set of templates for specific instrument modes. These requirements include:
In addition to these primary proposal tools, there are several other specialized tools you may want to investigate (e.g., target visibility tools, infrared background tool, etc.), depending on your science case.
The following resources are also available to help you with your proposal preparation:
JDox is a robust online resource designed to provide the astronomical community with accurate, user-friendly documentation related to the JWST observatory, instruments, and observation planning tools. With over 650 articles, there is a lot of information available on JDox. JDox is searchable with Google or by using the search tool within JDox itself.
While there is not one single way to proceed with proposing, here is an example work flow to provide some guidance. Feel free to adapt this to your own experience and learning style:
