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

| Input candidate:
|   Candidate index = 3
|   Segment [0] from curve   25
|      754 samples [   7.. 760]
|     0.123 of the curve [0.001__0.124]
|   Segment [1] from curve   27 (reversed)
|      768 samples [ 602..1369]
|     0.133 of the curve [0.104__0.237]
| Candidate after realignment and trimming:
|   Candidate index = 3
|   Segment [0] from curve   25
|      513 samples [  42.. 554]
|     0.083 of the curve [0.007__0.090]
|   Segment [1] from curve   27 (reversed)
|      513 samples [ 828..1340]
|     0.089 of the curve [0.143__0.232]

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