Hi,
here are the minutes of today's analysis meeting.
Attending DH,RM,KD,JC,OF,RF,AD,BT,MK,CC(speakerphone).
-Status ep elastic analysis (CC)
+See ppt
+Now based on v3_4_18
+Polarization product slightly larger than before
+"dip" near 0.3 (GeV/c)^2 still present - related to spin angle?
+Analysis performed with constant spin angle
+Use map instead to extract observables
-Status spin angle analysis
+New extraction of average spin angle from ep changed from 47.5+-0.8
to now 45.8 (!!) degrees using the Hoehler parametrization.
+Is now consistent with June2005 survey value (46.2)
+Reason is mostly due to new geometry which causes a slight shift in
theta_e
+ed-elastic analysis of spin angle is awaited (CZ)
+New results to be confirmed by d(e,e'p)
+Spin angle profile by Doug to be used
-Status Mascarad in Blast/Dgen
+Factor three discrepancy between original Mascarad and DGen
-Status missing forward angles in quasielastic MC
+Almost no events below 26 degrees
+Research in progress
Regards,
Michael
