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

| Input candidate:
|   Candidate index = 41
|   Segment [0] from curve   90
|      758 samples [ 816..1573]
|     0.106 of the curve [0.114__0.220]
|   Segment [1] from curve  108 (reversed)
|      745 samples [3090..3834]
|     0.156 of the curve [0.646__0.802]
| Candidate after realignment and trimming:
|   Candidate index = 41
|   Segment [0] from curve   90
|      513 samples [1008..1520]
|     0.072 of the curve [0.141__0.212]
|   Segment [1] from curve  108 (reversed)
|      513 samples [3141..3653]
|     0.107 of the curve [0.657__0.764]
