Comparison of different temperature analyses in units of 1000 K. Top: the optical-only analysis of Bestenlehner et al. (2020) against our optical-only (left) and our optical + UV analysis (right). Bottom: our optical-only (left) and our iron pseudo-continuum analysis (right) against our optical + UV analysis. The shaded are in the bottom right plot indicates the region that is not covered by the cmfgen grid that we used (Bestenlehner et al. 2014).
