| True and recognizable candidates
| Essentially entered by hand
| Some of them refined with PZRefineCands

| Input candidate:
|   Candidate index = 32
|   Segment [0] from curve    2
|      746 samples [3231..3976]
|     0.135 of the curve [0.583__0.717]
|   Segment [1] from curve   13 (reversed)
|      768 samples [ 353..1120]
|     0.133 of the curve [0.061__0.194]
| Candidate after realignment and trimming:
|   Candidate index = 32
|   Segment [0] from curve    2
|      513 samples [3466..3978]
|     0.093 of the curve [0.625__0.717]
|   Segment [1] from curve   13 (reversed)
|      513 samples [ 353.. 865]
|     0.089 of the curve [0.061__0.150]

| signal = "d" (difference of the two shape functions)
