Abstract
We present low resolution infrared spectral standards in the 0.76 to 5.0 mu m range based on JWST NIRspec Prism data from deep sky surveys. Our standards encompass spectral types M, L, and T and dwarf and subdwarf metallicity classes. The standards extend ground based spectral templates and enable classification of low temperature stellar substellar discoveries from deep JWST NIRSpec data.
