Relative error (ϵ) for ℋ (left) and ℒ (right) within a 0.5 × 0.5 × 0.2 pc³ at 153.3 kyr. We chose this box size to take into account the 0.5 pc of injection and a depth length similar to the filament scale (0.2 pc) to avoid the inclusion of background particles. The errors are calculated between X2 case and the rest. The panels are, from top to bottom: X1, X4, X8, X16 and X32. The bluer and redder indicate underestimation and overestimation of X2 relative to the others. The maximum and minimum errors for each comparison are written in the bottom-left corner. All green spheres have 0.065 pc radii.
