These are the starting conditions of the Calibrate Manually tab following simulated annealing of the radionuclide source strength distribution in the Surface Measurements tab.

Begin by adjusting the Dose Calibration slider until the dose profile curve passes through the 5 mm measurement point.

Adjust the Nearfield slope, Crossover and other nearfield related sliders to smooth the curve fit in the nearfield.

Adjust the Farfield power and Farfield threshold sliders to visually curve fit the data in the farfield.

Repeat steps 2-8 until the RMS error over the range 0..10 mm can no longer be reduced.

2. Next, adjust the Crossover slider to minimize the RMS error in the range 0..5 mm.
3. Next, adjust the Nearfield slope slider to minimize the RMS error in the range 0..5 mm.
4. Next, adjust the Anisotropy shift slider to minimize the RMS error in the range 0..5 mm.
5. Next, adjust the Anisotropy threshold slider to minimize the RMS error in the range 0..5 mm.
6. Next, adjust the Farfield power slider to minimize the RMS error in the range 0..10 mm.
7. Next, adjust the Farfield threshold slider to minimize the RMS error in the range 0..10 mm.
8. Next, adjust the Dose Calibration slider to minimize the RMS error in the range 0..5 mm.

You should always be able to achieve an RMS % error spanning the central axis of between 1 and 2%. NOTE: When the coarser slider controls are no longer effective at reducing the RMS error, use the bumper controls to change the patch source parameters by increments of .001.

Optionally, return to the surface measurements tab and resolve using the current starting parameters (i.e. do NOT click the distribute uniformly button, just click the solve button, and then repeat the manual fine tuning process). A second pass can sometimes improve the surface and axis curve fit by about 0.5 %.
