Top Maps of the percentages of the OD dispersion for the Gafchromic EBT3 film irradiated at nominal 3 Gy with the PMMA staircase for three zones (top, middle, bottom). Orange lines indicate the zone selected for the studied profile. Bottom absorbed doses in each PMMA step once the background is subtracted. The inset shows the average values in the middle of the steps (black dots) corresponding to each PMMA step.
