[09.June.2000]Some Distributions
Mass and angular distributions as computed using Adam's weights.

[13.June.2000]Status Report
A brief description of where things stand on 13 June, 2000.

[28.June.2000]Distributions from Dennis
Distributions as generated by Dennis. The alpha distribution deviates from those on June 9 because only one refelctivity is allowed.

[29.June.2000]Distributions for fit of unpolarized events
This is the one-bin sample that will be used in fitting.

Fit Results for the Polarized Blind Weight, (a2 bin)..

[28.July.2000]Second Blind Fit

[03.Aug.2000]Update on PWA.
We found an error in describing polarized events when alpha is not near 0 or 90.
We now understand the polarized and unpolarized amplitudes.

[05.Aug.2000]Adam's Results.
Results of Adam's fitting procedure to the "blind function".

[15.Aug.2000]Update on PWA.
Fits have been performed in 20 MeV mass bins from 1000-2000 MeV.
We are still waiting on the error code.

[20.Aug.2000]Scott and Adams Test.
IU Blind test performed by Scott on Adams fitting function.

[22.Sep.2000] Polarized Fits.
Results for fits to the polarized photon beam. These include detector resolution effects.

[23.Sep.2000] Unpolarized Fits.
Results for fits to the unpolarized photon beam.

[24.Sep.2000] Error Comparisons.
A comparison of errors from the 100% polarized and the unpolarized fits.

[30.Oct.2000]More Fits.
Fits to the blind weight using all waves that are in the weight, plus additional weights which are not in the the weight.
