JWST pure parallel observing programs obtain science data in fields of view that are dictated by unrelated prime observations. In this JWebbinar, we will review how pure parallel observations work and how to specify a pure parallel observation in the Astronomer’s Proposal Tool (APT). We will describe the new JWST pure parallel package, which facilitates statistical analysis of JWST pure parallel observing scenarios, based on historical data from previous observing cycles. We will work through a few example observing scenarios. Interested users are encouraged to install the package locally before the session. There will be plenty of time for questions.
