The observations provide the first spatially-resolved spectroscopy of the ejecta and equatorial ring (ER) over the 1-5 \\mu m range. We construct 3D emissivity maps of the [Fe I] 1.443 \\mu m line from the inner ejecta and the He I 1.083 \\mu m line from the reverse shock (RS), where the former probes the explosion geometry and the latter traces the structure of the circumstellar medium. We also present a model for the integrated spectrum of the ejecta. The [Fe I] 3D map reveals a hig","authors_text":"A. Coulais, A. Glasse, A. Rest, A. S. Hirschauer, B. Sargent, C. Fransson, G. S.
