MIRI Target Acquisitions

The JWST Mid-Infrared Instrument (MIRI) provides target acquisition (TA) capabilities for the low-resolution spectroscopy, medium-resolution spectroscopy, and coronagraphic imaging modes.

Overview of MIRI target acquisitions

Target acquisition (TA) is a procedure that centroids a source and places it accurately within an aperture, region of interest (ROI), or subarray. The filters available for MIRI TA are F560W, F1000W, F1500W, and FND. TA procedures are discussed in the context of the observatory in memos and reports by Gordon & Meixner (2008), Meixner et al. (2006), Nelan et al. (2005), and Meixner et al. (2004).  

TA procedures within the Astronomer's Proposal Tool (APT) are available for:
