====================== p=(20,30) pt=(0.0,0.2) ====================== tracks passing through vt2+mt COMMENTS: 1) altogether nice, good usual a/p > 95% 2) no real problems (split tracks, etc): 1 track with lost part 3) 1 completely crazy point glued (30cm)-see "strange stuff" 4) very tolerant joining of points to track (ca 1.5cm in mt), some doubts here, most ugly examples presented 5) error(b) sometimes enormous (100cm) -> mom.resolution ??? two categories are present in detailed description below: BAD- considered bad DOUBTS- causing any doubts (much less important) NOTE: it should not be surprising that enumerating does not include certain letters as some problems found are not present ofr this sample. -------------------------- overall statistics for bad -------------------------- problem positives negatives right side wrong side right side wrong side A) joined tr 0 0 1 0 B) large a/p 0 0 0 0 C) split cl.? 0 0 0 0 D) splits-serious 0 0 0 0 splits-candidates 0 0 0 0 E) lost parts 1 0 0 0 F) lost points 0 0 0 0 G) strange stuff 2 0 0 0 ------------------------------- overall statistics for doubts A(*) ------------------------------- 4 0 9 0 (*) the doubt about large distance for point seems to me important enough to be classified ========= detailed positives ========= BAD --- E) LOST PARTS 65: track lost after 11 points G) STRANGE STUFF 67: 1 vt1 point caught but track not going through vt1 !!! 83: strange y shift at 1 mt sector level, part of these points could come from another track --> note: apparently, this has been corrected after the scan DOUBTS ------ A) A/P OR LARGE DISTANCE FOR POINTS 4,58: points caught at large y distance 44,99: points caught at large y distance, could come from another track ========= detailed negatives ========= BAD --- A) JOINED TRACKS 97: by=6mm, track crossing: blue points should be lightblue?
