| True and recognizable candidates
| Essentially entered by hand
| Some of them refined with PZRefineCands

| Input candidate:
|   Candidate index = 31
|   Segment [0] from curve  105
|     1176 samples [  48..1223]
|     0.233 of the curve [0.010__0.242]
|   Segment [1] from curve  107 (reversed)
|     1163 samples [3932..5094]
|     0.128 of the curve [0.433__0.561]
| Candidate after realignment and trimming:
|   Candidate index = 31
|   Segment [0] from curve  105
|      513 samples [ 684..1196]
|     0.102 of the curve [0.136__0.237]
|   Segment [1] from curve  107 (reversed)
|      513 samples [3950..4462]
|     0.056 of the curve [0.435__0.491]
