Absolute spectrophotometry of quasars : Ton 469 (3C 232) and 3C 249.1. (1985). Revista Mexicana De Astronomía Y Astrofísica, 11(1), 121-126. https://astronomia.unam.mx/journals/rmxaa/article/view/1985rmxaa..11..121d

Abstract

Absolute intensities and equivalent widths for several lines not reported before are given for these two quasars. For TON 469, we find a ratio Mg II 2934/2798 which is higher (by a factor of about 2) than that found by Grandi and Phillips (1978) and we discuss the possibility and implications of its variation with time. We also discuss the excitation mechanism of Mg II 2934. For 3C 249.1, we have identified the following new lines: [Ne V] 3346, [Ne V] A3426 and He I 3889. Some commentaries are made on the continuum energy distribution of each object, after comparing with previous observations. In both cases optical continuum variability is confirmed.
