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

| Input candidate:
|   Candidate index = 5
|   Segment [0] from curve   37
|      982 samples [4119..5100]
|     0.181 of the curve [0.761__0.942]
|   Segment [1] from curve   44 (reversed)
|      982 samples [ 696..1677]
|     0.198 of the curve [0.140__0.338]
| Candidate after realignment and trimming:
|   Candidate index = 5
|   Segment [0] from curve   37
|      513 samples [4370..4882]
|     0.095 of the curve [0.807__0.902]
|   Segment [1] from curve   44 (reversed)
|      513 samples [ 916..1428]
|     0.103 of the curve [0.185__0.288]
