Recording

This training will introduce Roman’s Exposure Time Calculator (ETC), which allows users to assess the feasibility of their proposed observations by simulating astronomical scenes and providing accurate estimates of signal-to-noise ratios, among other things. These capabilities are especially relevant for the Cycle 1 Call for Proposals, which will fund data analysis, theory, and a small number of new observing proposals. Participants will learn Roman-specific planning terminology and strategies, gain hands-on experience using ETC to examine the capabilities of their proposed observations, and explore the capabilities of the Roman Community Defined Surveys in greater depth.

The training series is designed for users with all levels of experience. We will be providing a live, hands-on demo that can be viewed on its own. However, if a user wishes to actively follow along, the ETC is publicly available.
