The expected value was 0.5 mm, which is roughly twice the RFO.
Using the procedure described in Sec.II.A, the current DLG parameter for
our Trilogy MX equipped with the Millennium 120 MLC had been set to 2.4 mm. DLG values were chosen between the extremes to characterize the response, and finer resolution was used to select the DLG as the error decreased.
