  • aPercentage of molecules in the hyperrotated state compared to the total number of molecules as calculated from the fitted histogram.

  • bPercentage of molecules in the rotated state compared to the total number of molecules as calculated from the fitted histogram.

  • cPercentage of molecules in the nonrotated state compared to the total number of molecules as calculated from the fitted histogram.

  • dPercentage of the traces showing at least a single transition event between hyperrotated, rotated, and nonrotated states out of the total number of molecules.
