Intervening Fe i absorption towards the quasar HE 0001−2340: UVES 2001 spectrum (black curve) and simultaneous fit for the four transitions falling on the quasar continuum (red curve), thus excluding the Fe iλ2719 line, which falls on the quasar Lyα emission line. The green curve for the Fe iλ2719 absorption corresponds to a fit with a spatial coverage factor C_f,max = 0.37. At v_helio = 0 km s^-1, the redshift is z = 0.452060.
