Notes. (a)1 sr ~4.25 × 1010 square arcsecond. (b)Initial guesses of the fitting parameters. (c)Best-fit parameters. (1) Dust temperature for dust emission components and electron temperature for free-free emission component. (2) Solid angle of the emission components. (3) Dust column density. (4) Maximum (dust) grain size. (5) Emission measure for free-free emission component. (6) Dust mass in units of Earth mass (M⊕).
