$^\diamond$ Total NIR magnitudes were extracted within ellipses centred on the source and defined with the semi-major axis (SMA), the position angle (PA, relative to west axis and counter clockwise), and the eccentricity (Ecc.); $^\dagger$ The NIR extinction parameters were fixed to $JHK_{{\rm S}} = 0.07,0.03,$ 0.03 with an error of $\Delta ext/ext=0.2$.
