Observed SED of Par-Lup3-4. The circles show all photometric measurements. For the near-IR regime, the black circles represent 2MASS data, and the grey ones C03 data. The strong variability is responsible for the dispersion of the measurements taken at these wavelengths. The Spitzer IRS spectrum is shown in blue color. The best-fit models from our Bayesian analysis are represented by dotted (2MASS) and solid (C03) lines.
