_*Narbe:*_ Tabulated packing fractions, calculating errors similar to 
what was done for RSS. Has the preliminary results from some parallel 
and perpendicular runs. The perp runs seem to have very large errors. 
Will need some further study. Gave spreadsheet to Hoyoung for him to add 
his numbers, which are being corrected for tracking efficiencies.
Is going to continue working on getting dilution factors for the BETA data.

_*James:*_ Looked further at parallel raw asymmetries. Sorted by 
configuration, target cup, and field angle. Fitted with linear function. 
Sees trend for one group of runs. Oscar suggested getting systematics 
for making fits better. Mark mentioned correcting by beam and target 
polarizations.

Obtained average (charge-weighted) target polarizations sorted by 
configuration (energy,parallel/perp).



As always, please let me know if I missed something or made a mistake.

Next meeting will be July 14th.
