Table 1.

Pearson’s correlation coefficients between simulated velocities and FLCT-derived velocities at the base of the photosphere.

	FWHM [km]	O		OT		OTC
	FWHM [km]	r_{v_x}	r_{v_y}	r_{v_x}	r_{v_y}	r_{v_x}	r_{v_y}
Intensity	600	0.56	0.55	0.82	0.81	0.94	0.93
Intensity	300	0.51	0.51	0.83	0.83	0.92	0.91

B_z	600	0.61	0.58	0.83	0.83	0.94	0.94
B_z	300	0.68	0.64	0.90	0.90	0.93	0.93

Notes. The FLCT velocities are derived from the simulated intensity or the magnetic field at log τ₅₀₀ = 0. O: raw data; OT: velocities averaged over a 15-minute interval; OTC: velocities averaged over a 15-minute interval and convolved with Gaussian filter corresponding to the apodizing window used for FLCT.
