Hi all,
I have made adjustments to the paper as per the comments I have received
thus far -- thank you! I have also updated our results, where now the
g1/F1 proton fit takes into account the recent Hall B (EG1-DVCS) data.
The results on both g1/F1 neutron and the flavor-separated quantities
change a little, but well within out statistical precision. The
systematic error due to the g1/F1 proton fit has been updated accordingly
as well, with small changes resulting for g1/F1 neutron and the flavor
results. Overall, the up and down quark ratios tend to be smaller in
magnitude. In particular, the lowest x-bin on the down quark data now has
a value of +0.001, as opposed to -0.006 for the 5-pass data; however, its
statistical error is 0.182. The result averaged over 4- and 5-pass data
in that bin shows little change. You can download the latest version,
1.1, here:

Also, if you wish to compare the results for g1/F1 neutron and the flavor
data before and after the inclusion of the CLAS EG1-DVCS data in the g1/F1
proton fit, I have left version 1 available here:

Please send me your comments and suggestions within the coming week;
afterwards, I would like to circulate it to the larger Hall A
collaboration.
Best regards,
David
