Forward modeled observables and inferred quantities calculated from the Y. Fan & T. Liu (2019) MHD model using FORWARD and DKIST noise estimate for 12″ × 12″ spatial averaging. (a)–(e) are, respectively, the line peak amplitude (in millionth of the disk center brightness B at the wavelength), the measured Doppler LOS velocity, the line width, the linear polarization fraction (Stokes L/I), and the circular polarization fraction (Stokes V/I) of the 10747 Å line; (f) is the measured LOS magnetic field with signal-to-noise ratio above 3 inferred from the Stokes V/I.
