AB: Astronomers use certain bright stars, known as spectrophotometric standard stars, as standard candles from which to calibrate their instrumental intensity responses [\textit{Oke, 1990}, \textit{Hamuy et al.,1994}]. These response curves can then be used to intensity calibrate their object images and spectra in absolute units. Spectrophotometric standard stars are being used to intensity calibrate our archived high-resolution astronomical spectra of the night sky, so as to increase their utility for aeronomic research. There are several fairly bright spectrophotometric standards which together provide a calibration source that can be accessed and referenced to on a night to night basis. We discuss here the advantages and difficulties in using spectrophotmetric standard stars for calibration, the techniques that are employed by us and astronomers to calibrate high resolution astronomical spectra, and these techniques' general applicability to atmospheric observations.
