1. BeO target run 1893

using:
db_L.vdc.dat.00
before: db_run.dat without L.off_x,y,z [in specific run]
output: e07006_optics_1893.root.v00
After: db_run.dat with off_x,y,z from above Survey 
correct by the angle: theta_0 = 17.4997 deg
	off_x = Dx
	off_y = Dy*cos(theta_0)
	off_z = Dy*sin(theta_0)
	
output: e07006_optics_1893.root.v03

2. Optics C 13foils run 2013

using:
db_L.vdc.dat.00
db_run.dat with L.off_(x,y,z) 

/////now trying to use "OPTIC" script/////////
(once for each target) modify nfoil=13 in cut_L_Vertex.C

	analyzer .x cut_L_Vertex.C(runnumber)

(once for each target) modify Vertex.cut according to the foil cut from previous

	sh VertexTree2ascii.sh runnumber

(once for each target) modify const in LOpticsOpt.C

modify SourceDataBase, DestDataBase,RawDataFile in LOpticsOptScriptVertex.C

	analyzer .x LOpticsOptScriptVertex.C

now check result if satisfy change database and rerun

	sh DB_change.sh current_version
	sh ReRunRootFile.sh runnumber previous_version

now draw rpl.z
	analyzer .x drawchange.C(runnumber,previous_version)

	sh SaveGCut.sh runnumber previous_version
