Here, we present the first JWST transmission spectrum of LTT 1445 A b using a single visit spanning 3-5~$\\mu$m using NIRSpec/G395H. We conduct two independent reductions of the data using both the Eureka! and ExoTiC-JEDI pipelines. Overall, we measure the NRS1 transit depths to a median precision of $\\sim23$~ppm in 41 spectroscopic channels with uniform widths of 30 pixels ($\\sim$ 0.02 $\\mu$m), and the NRS2 transit depths to $\\sim36$~ppm ","authors_text":"Angie Wolfgang, Annabella Meech, Anna Gagnebin, Artyom Aguichine, Hannah R.
