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

| Input candidate:
|   Candidate index = 22
|   Segment [0] from curve   36
|      723 samples [2610..3332]
|     0.131 of the curve [0.475__0.606]
|   Segment [1] from curve   37 (reversed)
|      736 samples [3128..3863]
|     0.136 of the curve [0.578__0.714]
| Candidate after realignment and trimming:
|   Candidate index = 22
|   Segment [0] from curve   36
|      513 samples [2626..3138]
|     0.093 of the curve [0.478__0.571]
|   Segment [1] from curve   37 (reversed)
|      513 samples [3319..3831]
|     0.095 of the curve [0.613__0.708]
