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

| Input candidate:
|   Candidate index = 48
|   Segment [0] from curve   79
|      877 samples [1483..2359]
|     0.129 of the curve [0.218__0.346]
|   Segment [1] from curve   84 (reversed)
|      874 samples [4574..5447]
|     0.146 of the curve [0.762__0.907]
| Candidate after realignment and trimming:
|   Candidate index = 48
|   Segment [0] from curve   79
|      513 samples [1743..2255]
|     0.075 of the curve [0.256__0.331]
|   Segment [1] from curve   84 (reversed)
|      513 samples [4673..5185]
|     0.085 of the curve [0.778__0.863]
