Monte Carlo simulation results for second kind of surgical tool with various reference tool size l and working distance d. Null hypothesis for test 1 is: ${\mathbf{\Sigma }}_{\mathrm{sim}}={\mathbf{\Sigma }}_{\mathrm{pre}}$ and test 2 is $H_0:{\mu }_{\mathrm{sim}}={\mu }_{\mathrm{pre}},{\mathbf{\Sigma }}_{\mathrm{sim}}={\mathbf{\Sigma }}_{\mathrm{pre}}$
