_*James:*_ Applied preliminary dilution factors to physics asymmetries
A_1 and A_2. They look reasonable.

Will try applying the Oscar's live-time correction.
Working on using Oscar's live-time corrections.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Dead_Time#New_Livetimes:_6.2F1.2F2011
Will check to see if multiplying by the corresponding prescales.
Back to working on applying the elastic radiative tail correction.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Radiative_Corrections#Starting_to_Apply_Rad_Tail:_6.2F1.2F2011
Worked with Narbe to help optimize the dilution factor effort.

Giving a poster talk on SANE at the users' meeting

_*Anusha:*_ Compared single-arm(electron) and coincidence(proton) data
with and without azimuthal correction.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/C_runs_with_Perp._Field_ON#Checked_the_azim._ang._correction_with_Single_arm_electron.2FCOIN_proton_data
Looked at B-field direction with singles data (4.7GeV perp) comparing
with the B-field being reversed. This seems to show that the field
wasn't reversed.

Elastic dilution factors. Elastic peak aligns reasonably well to the
proton mass value.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Dilution_Factor_from_NH3
Will check scaling/weighting and use Hoyoung's packing-fractions (He
amount seems too high).
_*Hoyoung(06/02/11):*_ Tried applying Anusha's azimuthal correction to
data. Seems to cause more discrepancy between data and MC. The 2 MC's
(his and Anusha's) seems to be consistent, but the reconstruction
doesn't. Will look into this with Anusha and Narbe.

Working on using Oscar's live-time correction.
As always, please let me know if I missed anything or if I made any
mistake(s).
Next meeting will June 8th at 3:30pm JLab time.
