Determination of helical tilt angle range for residues 14-16 of M2δ domain. Using “experimental” values simulated for a 15° tilt angle, the ranges were determined for each residue by determining which A_exp values were within the acceptable error of +/-0.5 G. By varying the simulated helical tilt angles from 0°-90°, the ranges were calculated by finding the lowest and highest tilt angles that had A_exp values within the acceptable error of the “experimental” value. The values in red, blue, and green represent the A_exp values that were within the acceptable error of the experimental A_exp for residues 14, 15, and 16, respectively. The bolded values represent the lower and upper limits of the ranges. Moreover, the overall range obtained from the three residues is the range that is compatible with all three ranges, 14°-16°.
