Notes. The MODS spectral fitting parameters (after the outburst) are given after degrading the spectrum to the lower spectral resolution data of KOALA and FORS2 respectively. This allows for a meaningful comparison of the fitting parameters before and after the outburst, but not for a comparison between the two spectra before the outburst (i.e. FORS2 to KOALA). The observed FWHM is given in units of Å and the integrated flux in units of 10−14 erg cm−2 s−1.
