Output factors for IMRT– and SBRT–style fields from Clinac 2100, with sizes of 2×2 cm2, 3×3 cm2, 4×4 cm2, and 6×6 cm2. The graphs show the IROC–H data, results from simulations with PRIMO/DPM and PRIMO/PENELOPE, and measurements from this work with EBT3 film and a PinPoint 31014 chamber. Uncertainty bars show (with k=2) the standard deviation of the IROC–H data, the statistical uncertainty of the simulations, and the estimated experimental uncertainty of the measurements. For some data points, the bars are smaller than the symbol size. Data points for each field size are artificially separated along the horizontal axis for clarity
