Observing recommendations for JWST MIRI users

The Mid-Infrared Instrument (MIRI), a result of the collaborative work of a consortium of European and US institutes, is the only Mid-IR science instrument on the James Webb Space Telescope (JWST). The combination of MIRIs sensitivity and angular resolution over the 5-28.5 µm wavelength range will enable investigations into many different science topics, ranging from the local to the high-redshift Universe. The MIRI team has defined and published a set of”Recommended Strategies” to help observers optimally plan and execute their science programs. Some of these recommendations are generic and applicable to any science case; others are tailored to specific observing modes. Here we summarize key generic recommendations for MIRI observers, with emphasis on detector usage. All this information is available to observers as part of the James Webb Telescope User’s Documentation System and will be updated as needed.
