|   Segment [0] from curve   12
|      600 samples [1971..2570]
|     0.097 of the curve [0.319__0.416]
|   Segment [1] from curve   21 (reversed)
|      600 samples [1304..1903]
|     0.102 of the curve [0.223__0.325]
| Candidate after realignment and trimming:

|   Segment [0] from curve   12
|      513 samples [2014..2526]
