Halo-FDCA best-fit parameters.

I₀ (µJy arcsec²)	x₀ (deg)	y₀ (deg)	r_x (kpc)	r_y (kpc)	ϕ (rad)
1.82	230.33	30.68	418.7	212.7	2.14
0.03	0.0015	0.0017	8.2	4.4	0.018

Notes. Halo-FDCA best-fit parameters (top row) and uncertainties (bottom row) for the radio halo in A2061. The model assumed to fit the radio halo is a rotated ellipse, which has six free parameters. The reduced χ² of the best fit is 1.1.
