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

| Input candidate:
|   Candidate index = 26
|   Segment [0] from curve    8
|      934 samples [5212..6145]
|     0.138 of the curve [0.769__0.907]
|   Segment [1] from curve   19 (reversed)
|      930 samples [3181..4110]
|     0.179 of the curve [0.611__0.789]
| Candidate after realignment and trimming:
|   Candidate index = 26
|   Segment [0] from curve    8
|      513 samples [5291..5803]
|     0.076 of the curve [0.781__0.856]
|   Segment [1] from curve   19 (reversed)
|      513 samples [3520..4032]
|     0.099 of the curve [0.676__0.774]
