Result of the χ² minimization analysis for the PZ Tel companion. Plotted are the best value (asterisk) and the 1, 2, and 3σ error contours for effective temperature T_eff and logarithm of the surface gravity log g, determined from the comparison of our SINFONI spectrum and the Drift-Phoenix model grid. In addition, the temperature is shown as found by Mugrauer et al. (2010) (vertical solid blue line), including its 1σ errors (dashed lines), and surface gravity and temperature as found by (Biller et al. 2010) (green ellipse) and by Jenkins et al. (2012) (magenta part of ellipse).
