|   Segment [0] from curve   27
|      600 samples [1895..2494]
|     0.104 of the curve [0.328__0.432]
|   Segment [1] from curve   40 (reversed)
|      600 samples [2139..2738]
|     0.125 of the curve [0.445__0.569]
| Candidate after realignment and trimming:

|   Segment [0] from curve   27
|      513 samples [1938..2450]
