Hot Star Spectral Library (HST/STIS)


September 2017 version is available in a collection of FITS files or text files. This version has been put on a common logarithmic wavelength scale (see python code at the bottom of the page) and an extinction correction has been applied. The spectra are also available in the last column of the tables below.
