We measure the effective temperature of the qubit and characterize its relaxation and coherence times $\\tau_{1,2}$ for three devices in the temperature range of $20-300$ mK. We analyze the process of qubit thermalization to its effective environment consisting of multiple heat baths and support it with experimental data.
