Hi,
The way the power spectra with folding are computed currently is by changing the positions of particles according to
box_over_fold_x = box_x / fold inv_box_over_fold_x = 1.0 / box_over_fold_x x_pos = (x_pos % box_over_fold_x) * inv_box_over_fold_x
with fold = 2.0^folding, i.e. (from swiftsimio readthedocs)
fold = 2.0^folding
Should this not be x_pos = (x_pos % box_over_fold_x) * fold ?
x_pos = (x_pos % box_over_fold_x) * fold
For example, without folding (folding = 0 and fold =1) the positions are now converted to x_pos = (x_pos % (Lbox/1) ) * 1 / Lbox = x_pos / Lbox
x_pos = (x_pos % (Lbox/1) ) * 1 / Lbox = x_pos / Lbox
