Empirically derived gas temperature of the Antares atmosphere as a function of distance from the optical photosphere and projected radius. The filled blue diamonds are the values derived from the ALMA data, while the filled red circles are the values derived from the VLA data. The error bars on the gas temperature include the absolute flux density uncertainty and the fitting errors. The filled black circle at R_⋆ = 1 represents the photospheric effective temperature of 3660 K for Antares (Ohnaka et al. 2013).
