CS Pred 2 & 8 has been confirmed by manual check on plate 57

• Scanback (ID=100 & ID=200)

Pred 2 followed till plate 47 Pred 8 followed till plate 55

• TotalScan ID=1000

Pred 2 : done from plate 53 to plate 42  (1.2x1.2 cm2)
        Track reconstructed from plate 53 to 47
        Fedra vtx search : nothing
        Ariga-San display shows scattering -> try to follow the "new" track

        new pred:   ID=21  pl 43 :   60208.80   43129.95   0.1099   0.1992

        -> 21 & 22 are same BT on plate 43

Pred 8 : done from plate 57 to plate 50  (1.2x1.2 cm2)
        Track not reconstructed but BT found in CP files from plate 57 to 55
        Fedra vtx search : of course nothing
        Ariga-San display shows also scattering -> try to follow the "new" track

• New SB (ID=300)

Follow pred 81,21,22

        On plate 54, pred 81 found & also a MT on top with the same slope and position as the predicted BT from pred ID=8 !!!!

Pred 81, MT BOT OK but MT top FAKE    &  MT TOP found with seems to correspond to CS Pred 8

File:Mt found near pred id81 pl54.png

For info : CS pred 8 on plate 54 : 30058.69 29934.06 -0.1423 -0.0982

• Pred 81 stops at plate 42

New TotalScan  ID=3000
from pl 47 to pl 37 -> for Pred 81   (problem pl 45 like Peanut 2) :  STOP TS ID=3000 at plate 40 because fake stop -> continue SB ID=300

• SB ID=300

ID=81:
From plate 40 to 37, ID=81 not so clear, but nice on plate 36 & good plate 35  -> ID=81 stopped at plate 35 
-> continue TS ID=3000 from plate 39 to 30
CONFIRMED STOP at plate 35  :-(
(Remark BT found on plate 31 during SB is fake)

ID=22:
SB stopped at plate 38
-> TS ID=3000 of Pred ID=22 from pl 43 to 30  1.1x1.1 cm2 using intercalib from TS ID=81
On CP file plate 37 -> BT candidate  -> confirmed BUT 40 mrad in TX and 20 mrad in TY scattering
Pred 22 -> X=59233, Y=41583, TX=0.0724, TY=0.1800
-> FAKE STOP  track continue till plate 30
-> CONTINUE SB ID=300

• SB ID=300, Pred 22

Passing through

• TS ID=4000 from plate 43 to plate 29 using pred ID=81 with higher cutoff -> increase efficiency -> find muon ?

Re check light : 29050 ->  28460
CutOff 1  1250 -> 1200
CutOff 2  1250 -> 1200

Continue TS from plate 44 to 49 -> ID=4000, version=81 -> b098326.0.81.4000.operation.h

• TS from plate 57 to 50 ID=5000 -> b098326.0.1.400.operation.h

TS will be done as intercalibration , so create new pred file at plate without CS pred ID=2  -> 98326.57.1.400.pred.root
-> to run  scan5000.x
