[Sane-analysis] Minutes from March 31 Meeting

[Narbe Kalantarians]

_*Anusha:*_ Last week saw some correlations in plots of x, y, P-diff 
(diff = measured - predicted) vs. slow raster x & y. Found out sign for 
slow raster offsets was wrong.  This fixed things mostly. Still some 
correlations, which could be from slow raster size not being accounted 
for correctly.

Looked at BPMs (Tx & Ty) vs. HMS angle compared with P-diff vs. HMS 
angle. This showed things were changing as a function of angle. Updated 
plots with correct slow raster signs for offset, which are not yet 
posted. Will also look to see if there is a dependence on beam energy.

_*Jon:*_ Working on Cerenkov efficiencies. Looked at 15 parallel runs. 
Will provide an update next meeting.

Hovhannes/Narbe:*_ Added quasi-elastic and elastic part to cross-section 
in the Monte Carlo (GEANT). These are both from Peter Bosted's model. Do 
not see very much elastic events.

Got GEANT to now read in target densities. This way will allow for 
inputting various packing fractions for dilution factor studies. Only 
thing remaining for this is to get target component positions to also be 
read in from input files. Will do this very soon. Will get latest 
working copy of GEANT checked into CVS.

Oscar pointed out that the version of gcc on the JLab linux machines is 
very much antiquated. Got Steve Wood to install a more recent version on 
one of the CDAQ machines. Will look into possibly using this on Octavian.


_*Whit:*_ Set up MYSQL version of his databases, at Temple U, linked to 
wiki. This will provide easier access to useful Cerenkov and Neural 
Network information.

_*Luwani:*_ Wrote up an abstract for a poster talk on SANE at this 
year's INPC conference in Vancouver July 4-9. Sent it to mailing list also.

**As always, please let me know if I missed something or got something 
wrong.

Next meeting will be April 7th at 3:30pm
