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

| Input candidate:
|   Candidate index = 34
|   Segment [0] from curve   18
|      710 samples [5268..5977]
|     0.115 of the curve [0.856__0.971]
|   Segment [1] from curve   36 (reversed)
|      696 samples [4137..4832]
|     0.127 of the curve [0.752__0.879]
| Candidate after realignment and trimming:
|   Candidate index = 34
|   Segment [0] from curve   18
|      513 samples [5315..5827]
|     0.083 of the curve [0.864__0.947]
|   Segment [1] from curve   36 (reversed)
|      513 samples [4288..4800]
|     0.093 of the curve [0.780__0.873]
