Notes. Best-fit parameters for the four models of disk and/or envelope explored to reproduce the emission of K04166 and K04169 at 1.4 mm. (a)P, G, D, PD, and PG stand for Plummer-envelope-only, Gaussian-disk-only, uniform-disk-only, Plummer-envelope+uniform-disk, and Plummer-envelope+Gaussian-disk models, respectively (see Maury et al. 2019 for more description of the modeling of visibilities). (b)The disk radius reported is either the Gaussian FWHM for the Gaussian disk model, or the radius from the uniform disk model. The radii in astronomical units are given, using a distance of 156 pc. (c)χ2 corresponds to the χ2 per degree of freedom (reduced χ2). (d)Reports whether the model is the best at reproducing the data according to the F-test.
