|   Segment [0] from curve   20
|      600 samples [4210..  44]
|     0.126 of the curve [0.884__0.009]
|   Segment [1] from curve   36 (reversed)
|      600 samples [4228..4827]
|     0.109 of the curve [0.769__0.878]
| Candidate after realignment and trimming:

|   Segment [0] from curve   20
|      513 samples [4253..   0]
