These observations are associated with JWST GO program 2282 and HST GO programs 14096, 15842, and 16668. The data (doi:10.17909/cqfq-5n80) were obtained from the Mikulski Archive for Space Telescopes (MAST) at the Space Telescope Science Institute (STScI), which is operated by the Association of Universities for Research in Astronomy (AURA), Inc., under NASA contractNAS 5-03127 for JWST.
