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

| Input candidate:
|   Candidate index = 18
|   Segment [0] from curve   84
|      780 samples [3223..4002]
|     0.130 of the curve [0.537__0.666]
|   Segment [1] from curve   91 (reversed)
|      801 samples [1684..2484]
|     0.113 of the curve [0.239__0.352]
| Candidate after realignment and trimming:
|   Candidate index = 18
|   Segment [0] from curve   84
|      513 samples [3404..3916]
|     0.085 of the curve [0.567__0.652]
|   Segment [1] from curve   91 (reversed)
|      513 samples [1792..2304]
|     0.073 of the curve [0.254__0.326]
