### OF Measurements  
The OF values, obtained using all the dosimeters for all the tubular applicators and beam energies, are shown in Figure 4. OF values were reported as a function of nominal field size, defined as the applicator diameter. OFs measured by the solid-state detectors agreed with those measured with the ionization chamber within 1.7% for the 50 mm diameter, as can be seen in Table 5. It is noteworthy that the microsSilicon got the best agreement with the ionization chamber, with a maximum deviation of 0.8%. \begin{table}
