Evaluation of the error in the recorded beam pointing angle due to truncation by an aperture. (a) We simulate a Gaussian pulse intensity that is tilted towards a one-dimensional binary mirror edge, denoted by the red arrow. (b) With increasing pointing angle, the mirror edge intersects different points of the beam intensity; all pulse energy outside this mirror edge is lost. (c) Simulations of a 9.32 keV beam described by the parameters of our empirical model, intersecting the HOM1 mirror of the SPB/SFX instrument.
