a Crystal structure of the tP2 FePd unit cells with disorder parameters 0, 0.5, and 1. b Schematic of a multi-beam off-zone axis (MBOZA) condition showing beam-sample orientation and the intersection (blue dashed line) between zeroth-order Laue zone (ZOLZ) and the Ewald sphere. c \({F}_{g}^{X}(0,\,1)\) - \({F}_{g}^{X}(0,\eta )\) (\(h+k+l\) odd, \({B}_{{\mbox{iso}}}\) fixed at 0) as a function of s for η = 0, 0.2, 0.4, 0.6, and 0.8. d \({F}_{g}^{X}({B}_{{\mbox{iso}}},1)\) - \({F}_{g}^{X}(0,\,1)\) (\(h+k+l\) even, η fixed at 1) as a function of s for \({B}_{{\mbox{iso}}}\) = 0.1, 0.2, 0.3, 0.4, and 0.5. Grey rectangular shadows in (c, d) highlight the behaviour of low-order \({F}_{g}^{X}\) from (001) to (222) with s ranging from 0.131 to 0.455 Å-1. Source data are provided as a Source Data file.
