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

| Input candidate:
|   Candidate index = 49
|   Segment [0] from curve   25
|      526 samples [1128..1653]
|     0.086 of the curve [0.184__0.269]
|   Segment [1] from curve   40 (reversed)
|      529 samples [2131..2659]
|     0.110 of the curve [0.443__0.553]
| Candidate after realignment and trimming:
|   Candidate index = 49
|   Segment [0] from curve   25
|      513 samples [1153..1665]
|     0.083 of the curve [0.188__0.271]
|   Segment [1] from curve   40 (reversed)
|      513 samples [2129..2641]
|     0.107 of the curve [0.442__0.549]
