CCM reddening-corrected IUE spectrum (with the exception of V446 Her: HST-STIS) and the power-law approximation to the continuum SED for ten old novae in the sample. The strong noise generally present between 2000 and 2400 Å is due to the low sensitivity in this range of the IUE LW cameras. For the faintest objects, a modest rebinning has been applied in this wavelength region.
