Data analysis of adiabatic R1ρ, adiabatic R2ρ, and R1 at single (18.8 T), two (14.1 and 18.8 T), or three (14.1, 16.5, and 18.8 T) magnetic fields using the geometric approximation. At these three magnetic fields, 300 relaxation data sets were simulated using the Bloch−McConnell equation with random input dynamic parameters. The fit results are plotted against the input values, and those with large standard deviations (SD of kex > 100.2, SD of Δω > 0.4 ppm, SD of pa > 2.5%) during Monte Carlo sampling are not shown. The coefficient of determination (R2) was calculated for each dynamic parameter. The numbers in parentheses are the percentages of data that remained after the results with large standard deviations were filtered out.
