Description:
Infrared spectra with increased spectral resolution and accuracy of
the absolute infrared spectral flux have been created for a subset of
stellar standards created by Cohen and his collaborators in previous
papers in this series. Moderate-resolution
(λ/Δλ∼400) spectroscopy obtained on infrared
standard stars by the Short Wavelength Spectrometer on the Infrared
Space Observatory was combined with high-quality photometry tied to
our recent absolute calibration from the Midcourse Space Experiment.
Thus, 1-35 micron spectra were created for 33 stars, 9 of which are
Cohen et al. secondary standards and another 20 of which are tertiary
standards for which Cohen adopted spectral templates.
The wavelength spacing is given by (0.0001/1 micron)*lambda^2, which
provides for 10,000 samples over the 1-35 micron spectral range
