Crystal in reciprocal space
Try peak_finder_v3
We try to use peak_finder_v3 with parameters (see Peak finders for more detail. ).

alg_arc = PyAlgos(windows=winds_arc, mask=mask_arc, pbits=0)
alg_arc.set_peak_selection_pars(npix_min=5, npix_max=100, amax_thr=0, atot_thr=2000, son_min=6)
alg_equ = PyAlgos(windows=winds_equ, mask=mask_equ, pbits=0)
alg_equ.set_peak_selection_pars(npix_min=5, npix_max=100, amax_thr=0, atot_thr=2000, son_min=6)
...
peaks_arc = alg_arc.peak_finder_v3(nda, rank=5, r0=5, dr=0.05)
peaks_equ = alg_equ.peak_finder_v3(nda, rank=5, r0=5, dr=0.05)

It finds approximately 3× more (seed) peaks with higher atot_thr than peak_finder_v2.
This makes event selection more complicated and in result the same matching algorithm finds 4× less peaks.
