Using spectral ratios, we can propagate Kurucz models of the A dwarfs to the K giant HR 6348, which can then serve to calibrate the remaining database of SL spectra. Mitigation in the vicinity of the Pfund-a line is necessary to reduce residual artifacts at 7.45 um. In general, the new SL spectrum of HR 6348 has a spectroscopic fidelity of ~0.5% or better.
