These stars -- Beta Peg, Alpha Boo, Beta And, Beta Gem, and Alpha Hya -- augment our already created complete absolutely calibrated spectrum for Alpha Tau. All these spectra have a common calibration pedigree. The wavelength coverage is ideal for calibration of many existing and proposed ground-based, airborne, and satellite sensors.
