Top panel: when compared to HST NUV flux measurements, the BT-Settl PHOENIX models nearly always underpredict NUV fluxes for FGKM stars, with the discrepancy increasing with decreasing temperature. In all cases, the model-predicted fluxes are within a factor of 2. The two instances where the model flux exceeds the observations coincide with HST spectra that have excessive noise and gaps shortward of 2100 Å. Bottom panel: when compared to GALEX flux measurements, the BT-Settl PHOENIX models underpredict NUV flux for M stars at levels similar to the HST data, but predict larger flux values for FGK stars. All but one of the FGK stars in this plot fall within the nonlinear regime in the NUV GALEX detectors, requiring a white dwarf correction, which may yield significant uncertainty.
