Evaluation of Retardation by Average Value Re
The following four tables summarize the relationship between rubbing strength and retardation magnitude. In order to make it intuitive and easy to understand, I have divided the retardation magnitude into three groups and displayed them by color. Blue is greater than 1 nm, yellow is 0.5 to 1 nm, and red is less than 0.5 nm.
