Multiwavelength light curves of 3C 279 in 1992 December–1993 January, showing (a) dereddened optical R‐band fluxes (from Grandi et al. 1996); (b) dereddened IUE fluxes at 2600 Å; and (c) deabsorbed fluxes at 1 keV for Galactic ﹩N_{\mathrm{H}\,\,{}^{{\rm{\small I}}}}=2.22\times 10^{20}﹩ cm−2 (from Sambruna 1997). Error bars represent 1 σ uncertainties.
