Abstract:
    We present five new absolutely calibrated continuous stellar spectra
    from 1.2 to 35 um, constructed as far as possible from actual observed
    spectral fragments taken from the ground, the Kuiper Airborne
    Observatory (KAO), and the IRAS Low Resolution Spectrometer (LRS).
    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.
