| Input candidate:
|   Candidate index = 19
|   Segment [0] from curve   17
|      864 samples [ 835..1698]
|     0.188 of the curve [0.181__0.369]
|   Segment [1] from curve   22 (reversed)
|      886 samples [1044..1929]
|     0.230 of the curve [0.271__0.500]
| Candidate after realignment and trimming:
|   Candidate index = 19
|   Segment [0] from curve   17
|      513 samples [ 867..1379]
