The JWST HST Alignment Tool (JHAT) is an open-source Python tool for providing relative and absolute astrometric alignment for JWST and HST level 2 and level 3 images. The tool has a novel source finding and matching algorithm that is excellent for alignment images to either other images or reference catalogs, even in sparse fields. The code has been tested on JWST NIRCam, FGS, and MIRI, as well as HST WFC3 (IR+UVIS) and ACS. The JHAT package is pip installable.
