Extraction of Predictions from DB: done. OK.
Reading Corner, creating mapfile: done. OK.

Manual Check of Predictions: done. NOT FOUND.
(neither by Frank, nor by Frederic, nor by Ciro).

Started large area scan (2x2cm2) around point containing the two predictions.
Up to plate 43.

Mark Problem: some optical marks printed twice. Plate cannot be used for scannning at all.
This affects Plate 54,51,45.
Mark Problem: Plate 53 was rotated by about 5degree, big alignment offset necessary. After this plate can be aligned.

See tracks passing the 12 scanned plates, but no good >2 prong vertices, and the 2prong vertices have all low 
probability (long track+a short track: may be accidentaly).

Shower search. done. NOT FOUND.
