Before revision:  When disentangling systematic and random properties of the order parameter distribution, related to the tilt angle and the fluctuations , respectively, a more detailed picture of the impact of sterols can be formulated, revealing, e.g., an approximate temperature-concentration superposition ranging from the liquid to the gel phase.
After revision:  When disentangling the overall tilt angle and the fluctuations , respectively, a more detailed picture of the impact of sterols can be formulated, revealing, e.g., an approximate temperature-concentration superposition ranging from the liquid to the gel phase.
