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

| Input candidate:
|   Candidate index = 9
|   Segment [0] from curve   63
|      800 samples [1487..2286]
|     0.099 of the curve [0.184__0.283]
|   Segment [1] from curve  102 (reversed)
|      812 samples [4512..5323]
|     0.104 of the curve [0.577__0.680]
| Candidate after realignment and trimming:
|   Candidate index = 9
|   Segment [0] from curve   63
|      513 samples [1516..2028]
|     0.064 of the curve [0.188__0.251]
|   Segment [1] from curve  102 (reversed)
|      513 samples [4781..5293]
|     0.066 of the curve [0.611__0.677]
