| Input candidate:
|   Candidate index = 24
|   Segment [0] from curve   20
|     1042 samples [ 118..1159]
|     0.219 of the curve [0.025__0.243]
|   Segment [1] from curve   37 (reversed)
|     1054 samples [1778..2831]
|     0.195 of the curve [0.329__0.523]
| Candidate after realignment and trimming:
|   Candidate index = 24
|   Segment [0] from curve   20
|      513 samples [ 252.. 764]
|     0.108 of the curve [0.053__0.160]
|   Segment [1] from curve   37 (reversed)
|      513 samples [2187..2699]
|     0.095 of the curve [0.404__0.499]
