[d2n-analysis-talk] A_1^n Statistical Error Technical Note (Update)

[David Flay]

Hi all,

I have made corrections to the A_1^n statistical error technical note,
adding superscripts to the quantities N_p, N_cut, and N_raw.

I have also included the 4-pass error bars in the plot on the last page. 
I did <not> skew the positions of the 4-pass points on this plot, so what
you see is what you get; therefore, the 4-pass points are in good
agreement with what we see at 5-pass, for those overlapping data points. 
In one case (x ~ 0.633) the error bar is reduced by about a factor of 2
(4% at 5-pass to ~1.8% at 4-pass).

You can find the (main directory) updated note (v3) here:

I would still like to investigate the quantities R and D, as brought up by
Greg in the meeting yesterday.

Thanks,

Dave

P.S. -- Still looking for ways in ROOT to generate that error band at the
bottom of a plot, so I can insert the E99-117 systematic errors on their 3
data points...
