Axial normalisation factors for span-1 and span-11. a: Span-1 axial factors for the true events, derived from a long phantom acquisition and the provided span-11 axial factors; shown only for the first 190 sinogram planes (which constitute the first three segments of 64 + 2×63 sinogram planes) out of the total of 4084 sinograms. b: Span-11 geometric axial factors provided with the component normalisation file. c: Scatter specific span-1 axial factors derived from a high statistics phantom acquisition (only the first 190 sinogram plane factors are shown). d: Scatter span-11 axial factors, also derived from a phantom acquisition
