Slit locations for four separate visits. Our target, JADES-GS-z14-0, was observed using the MIRI/LRS in slit mode across four separate visits with two dithers along the slit nod for each visit. We show the eight distinct slit locations alongside the JWST/NIRCam imaging (using F444W-F277W-F115W filters as an RGB false-color mosaic). MIRI/LRS’s slit size is ﹩4.7\,{\rm{arcsec}}﹩ in length and ﹩0\mathop{.}\limits^{\unicode{x02033}}51﹩ in width. Three-fourths of the observations were successful in placing JADES-GS-z14-0 within the slit (observations #2, #3, and #4); the remaining one-fourth of the observations were not successful because of failed target acquisition caused by an anomalous cosmic-ray event (observation #1).
