|   Segment [0] from curve   46
|      600 samples [3229..3828]
|     0.097 of the curve [0.522__0.619]
|   Segment [1] from curve   67 (reversed)
|      600 samples [1009..1608]
|     0.065 of the curve [0.109__0.174]
| Candidate after realignment and trimming:

|   Segment [0] from curve   46
|      513 samples [3272..3784]
