Context. FeII emission is a well-known contributor to the UV spectra of active galactic nuclei and modeling this part may affect results obtained for MgII λ 2800 emission, which one lines used black hole mass measurements cosmological applications. Aims. We tested different models when intermediate-redshift quasar HE 0413−4031 see how use specific template affects line properties measurement time delays with respect continuum. Methods. 11-year monitoring selected South African Large...

Fe II emission is a well-known contributor to the UV spectra of active galactic nuclei and modeling this part may affect results obtained for MgII$\lambda2800$ emission, which one lines used black hole mass measurements cosmological applications. We use 11-year monitoring selected quasar HE 0413-4031 with South African Large Telescope (SALT) we supplement near-IR spectrum taken SOAR telescope. A new redshift determination ($z=1.39117 \pm 0.00017$) using [OIII]$\lambda \lambda 4959,5007$ gave...
