Frequency histograms of programmed leaf open times for both original and increased pitch plans taken from normalized leaf timing sinograms. Fractional leaf open times are relative to a projection interval of 294 ms. In all cases, increasing the pitch resulted in an increase in the mean leaf open time as well as an increase in the actual modulation factor.
