Errors in the reconstructed traction field, $e_2(\mathbf{t})$ and $e_{\infty }(\mathbf{t})$ (see Eqs. (9) and (10)), for the microglial cell

	NL-CUR		LIN		NL-REF
Error	$\eta =1\%$	$\eta =5\%$	$\eta =1\%$	$\eta =5\%$	$\eta =1\%$	$\eta =5\%$
$e_2(\mathbf{t})$ (%)	14.1	25.5	23.9	27.7	23.6	27.1
$e_{\infty }(\mathbf{t})$ (%)	11.5	20.0	38.4	30.1	44.2	35.3

Results are shown for the new approach (NL-CUR), the linear elasticity approach of Ref. [24] (LIN), and the nonlinear approach of Dong and Oberai [29] (NL-REF), at noise level $\eta =1\%$ and 5%.
