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

| Input candidate:
|   Candidate index = 37
|   Segment [0] from curve   39
|      749 samples [1986..2734]
|     0.143 of the curve [0.380__0.524]
|   Segment [1] from curve   43 (reversed)
|      754 samples [4290..5043]
|     0.145 of the curve [0.827__0.972]
| Candidate after realignment and trimming:
|   Candidate index = 37
|   Segment [0] from curve   39
|      513 samples [2080..2592]
|     0.098 of the curve [0.398__0.497]
|   Segment [1] from curve   43 (reversed)
|      513 samples [4439..4951]
|     0.099 of the curve [0.856__0.954]
