|   Segment [0] from curve   17
|      600 samples [1011..1610]
|     0.130 of the curve [0.220__0.350]
|   Segment [1] from curve   29 (reversed)
|      600 samples [2590..3189]
|     0.076 of the curve [0.329__0.405]
| Candidate after realignment and trimming:

|   Segment [0] from curve   17
|      513 samples [1054..1566]
