The performance of JWST's Mid-Infrared Instrument (MIRI) is predicted by a model that uses a number of parameters derived from laboratory measurements.
The performance of MIRI has been studied in detail by Glasse et al. (2015) and Boccaletti et al. (2015). These studies bring together performance metrics from laboratory testing with a sensitivity model formulated by Swinyard et al. (2004). These models have been adapted by the Exposure Time Calculator (ETC). Operational overheads (Gordon et al. 2014), including target acquisition, small angle maneuvers to allow efficient background subtraction, time spent moving MIRI mechanisms, or taking calibration observations are incorporated and included in the final time calculated by the Astronomer's Proposal Tool (APT).
