Upper panel: the ratio of the observed binned STIS spectra used to fit the blackbody excess model and the disk models binned to the same wavelength sampling. Notice that for all the FUOrs in the sample, the NUV flux is at least 2× as bright as the disk model predicts at 2200 Å and for many, the flux ratio is > 10 (for HBC 722 and V1057 Cyg, this is true at 2400 Å, despite the lack of data at 2200 Å). Lower panel: the L_excess measurements for each of the FUOrs compared with their disk-model-derived L_acc. The error bars on each point are given by the 1σ ranges of their posterior distributions. The mean and standard deviation on the UV excess luminosities (excluding BBW 76) are marked by the purple line and shading, respectively.
