|   Segment [0] from curve   89
|      600 samples [4095..4694]
|     0.089 of the curve [0.605__0.693]
|   Segment [1] from curve  107 (reversed)
|      600 samples [4257..4856]
|     0.066 of the curve [0.468__0.534]
| Candidate after realignment and trimming:

|   Segment [0] from curve   89
|      513 samples [4138..4650]
