Influence of the chosen aperture radius and the baseline modelling. We present the same light curve (at 3.6 μm, 2008 January 30, AOR: 24882688) four times, however showing different noise level and a different occultation depth due to the data reduction and analysis. On the left, the aperture photometry is centred by a 2D elliptical Gaussian fit with an aperture radius of 1.9 pixels, while on the right the aperture radius equals 3.5 pixels. They all proceed to the same MCMC analysis with the inferred parameters from Table 3, except that the top ones contain a baseline model dealing with the measured PSF FWHM, while the bottom ones do not.
