Logarithmic of the normalized intensity maps in the H band for the two models used in this paper. Left: RvZ model computed with the CHARRON code with the model parameter values given by Domiciano de Souza et al. (2014). Right: HDUST model with an ellipsoidal photosphere similar to the RvZ model and a circumstellar viscous decretion disk model (further details in Faes 2015, Chap. 6). The flux ratio of photosphere and disk model relative to the purely photospheric emission is 1.023.
