Fig. 4
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 Teff and optical extinction AV, determined from the comparison of our SINFONI spectrum and the Drift-Phoenix model grid. In addition, the visual extinction of PZ Tel A is shown (horizontal solid brown line), including its 1σ errors (dashed lines) as found by Bailer-Jones (2011).
