MIRI Sensitivity

The MIRI science team has provided the following tables for the MIRI photometric and spectrograph sensitivities. All estimates assume a low zodiacal background (important below 10 microns), a point source, and 10 sigma measurement after 10,000s. For more detailed information please see MIRI Performance
