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

| Input candidate:
|   Candidate index = 25
|   Segment [0] from curve   20
|      551 samples [4191..4741]
|     0.116 of the curve [0.880__0.995]
|   Segment [1] from curve   30 (reversed)
|      551 samples [1248..1798]
|     0.192 of the curve [0.435__0.627]
| Candidate after realignment and trimming:
|   Candidate index = 25
|   Segment [0] from curve   20
|      513 samples [4209..4721]
|     0.108 of the curve [0.883__0.991]
|   Segment [1] from curve   30 (reversed)
|      513 samples [1262..1774]
|     0.179 of the curve [0.440__0.618]
