1. In simulations, several other methods such as the chain-length dependence of the chain radius of gyration [12, 54] and the peak in the specific heat [27, 28] are commonly used to determine the Θ point. We need to stress that these methods are based on the consequences of the rigorous definition of the Θ point via the second osmotic virial coefficient under certain approximations; they are not definitions in themselves. Due to the use of these approximations, the Θ point determined using these methods are not very accurate.
