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

| Input candidate:
|   Candidate index = 15
|   Segment [0] from curve   99
|      574 samples [2222..2795]
|     0.080 of the curve [0.309__0.388]
|   Segment [1] from curve  104 (reversed)
|      565 samples [2567..3131]
|     0.176 of the curve [0.799__0.975]
| Candidate after realignment and trimming:
|   Candidate index = 15
|   Segment [0] from curve   99
|      513 samples [2303..2815]
|     0.071 of the curve [0.320__0.391]
|   Segment [1] from curve  104 (reversed)
|      513 samples [2549..3061]
|     0.160 of the curve [0.794__0.953]
