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

| Input candidate:
|   Candidate index = 29
|   Segment [0] from curve   88
|      915 samples [ 235..1149]
|     0.147 of the curve [0.038__0.185]
|   Segment [1] from curve  107 (reversed)
|      917 samples [2460..3376]
|     0.101 of the curve [0.271__0.371]
| Candidate after realignment and trimming:
|   Candidate index = 29
|   Segment [0] from curve   88
|      513 samples [ 276.. 788]
|     0.082 of the curve [0.044__0.127]
|   Segment [1] from curve  107 (reversed)
|      513 samples [2824..3336]
|     0.056 of the curve [0.311__0.367]
