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

| frb_analyze
|   maxShift =    0.847 pixels
|   nSamples = 513

| Input candidate:
|   Candidate index = 42
|   Segment [0] from curve    4
|      785 samples [ 730..1514]
|     0.126 of the curve [0.117__0.244]
|   Segment [1] from curve   16 (reversed)
|      759 samples [5033..5791]
|     0.105 of the curve [0.698__0.804]
| Candidate after realignment and trimming:
|   Candidate index = 42
|   Segment [0] from curve    4
|      513 samples [ 914..1426]
|     0.083 of the curve [0.147__0.230]
|   Segment [1] from curve   16 (reversed)
|      513 samples [5107..5619]
|     0.071 of the curve [0.709__0.780]

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