Target acquisition (TA) is generally not required for MIRI imaging observations. For the special case of high precision photometry of bright sources, such as time-series observations (TSOs), TA may be desired.

Target acquisition for MIRI imaging currently unsupported

The MIRI imager can be used to obtain high precision photometry of bright sources that may be useful for time-series observations (TSOs). Given the high stability and photometric precision required for such observations, target acquisition (TA) is usually recommended to ensure that the target is very accurately placed in the nominal pointing position for the required subarray. This is particularly important for repeated observations, where different exposures will be combined.

TA for MIRI imaging is not currently supported, but is expected to be available in the future.
