'''Final SB ID=500 -> merge ID=200 & ID=300 & TS ID=2 plate 11 to 1'''
'''b098326.0.1.500.stopping_point.txt'''
'''TS from plate 57 to 29 : 98326.plate.81.4000.cp.root in dset_TS'''

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

[[Image:Event.png]]

* '''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

[[Image:Sbtrk2 x.gif]] [[Image:Sbtrk2 y.gif]]

new pred: ID=21 pl 43 : 60208.80 43129.95 0.1099 0.1992
ID=22 pl 46 : 60740.25 43956.61 0.1462 0.2188
-> 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

[[Image:Sbtrk8 xview.gif]] [[Image:Sbtrk8 yview.gif]]

new pred: ID=81 pl 54 : 30050.46 29953.10 -0.0423 0.0175

* '''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 !!!!'''

[[Image:Image1.png]]

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

[[Image: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
directory : dset_TS_81_stp_point
Candidate Plate 32, try to follow it : 98326.1.32.310.pred.root -> FAKE
'''MUON found''' -> Vertex 2 prong found Muon on plate 43 : 10 35619.98 29058.14 0.3910 -0.0922 0

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
directory : dset_TS_plate_57_50_2x2cm2

* TS from plate 57 to 50, ID=6000 -> b098326.0.1.500.operation.h
-> 98326.57.1.400.pred.root
1.6x1.6 cm2
changed in VS5 Z threshold 100->200 and thickness 30->27

* dset
dset_TS_2 : 1st TS Pred ID=2, plate 53 to 42 -> no confirmed stop of CS Pred ID=2, files=98326.plate.2.1000.cp.root
dset_TS_22 : Last TS of Pred ID=22, plate 21 to 1 -> Passing through. files=98326.plate.22.3000.cp.root
dset_TS_22_plate43to31 : TS of Pred ID=22, plate 43 to 30 -> no confirmed stop of Pred ID=22, files=98326.plate.22.3000.cp.root
dset_TS_8 : 1st TS Pred ID=8, plate 57 to 50 -> no confirmed stop of CS Pred ID=8, files=98326.plate.8.1000.cp.root
dset_TS_81_3000 : TS of Pred ID=81, plate 47 to 31 (stopping point at plate 35), files=98326.plate.81.3000.cp.root -> Confirme stop ?
dset_TS_81_stp_point : redo TS with lower cutoff of Pred ID=81, plate 43 to 29 , files=98326.plate.81.4000.cp.root
dset_TS_plate_57_50_2x2cm2 : TS near 2x2 cm2, plate 57 to 50, all predictions except 2, try to reconstruct secondary interaction on plate 54, files=98326.plate.1.5000.cp.root
dset_TS_plate_57_50_1.6x1.6cm2 : TS 1.6x1.6 cm2 same as previous but change settings VS5 about thickness, files=98326.plate.1.6000.cp.root

No coscmics => Lateral marks

In X-marks frame:

Corners: -314,-665, 124848, 98789.9,

Marks: 119991.6, 96203.5, 119995.7, 1477.6

This means second lateral mark from the left side (with round hole) in emulsion.
