Translational and rotational temperatures of the neutrally buoyant Brownian particle trapped in a harmonic potential in a stationary fluid medium as a function of the bond constant k. The nondimensionalized characteristic memory times are ${\tau }_1/{\tau }_{\nu }=0.12$ and ${\tau }_2/{\tau }_{\nu }=0.088$. The error bars have been plotted from standard deviations of the temperatures obtained with 15 different realizations, consisting of 100,000 time steps per realization.
