| 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 = 46
|   Segment [0] from curve   88
|      690 samples [4631..5320]
|     0.111 of the curve [0.744__0.855]
|   Segment [1] from curve  106 (reversed)
|      688 samples [ 824..1511]
|     0.105 of the curve [0.126__0.231]
| Candidate after realignment and trimming:
|   Candidate index = 46
|   Segment [0] from curve   88
|      513 samples [4679..5191]
|     0.082 of the curve [0.752__0.834]
|   Segment [1] from curve  106 (reversed)
|      513 samples [ 948..1460]
|     0.078 of the curve [0.145__0.223]
|

| signal = "d" (difference of the two shape functions)
| 
| flip-doubled Fourier transform
