[b1_ana] slides

Mon Jun 17 11:24:32 EDT 2013

Additionally, on Slide 31, we'll want to make clear that the column on the bottom table labeled "Drift Error" is actually δAzz, not δξ. The statistics listed in the same table are the statistics for each spectrometer setting (aka the blue and red settings), not the rebinned x ranges (purple).

At Pzz=20%, the calculated statistics (and #s for the systematics, if we need them) for the rebinned x-ranges are (slightly optimized from the proposal):

<x> & dAzz Stat & dAzz Sys
0.16 & 2.48E-3 & 4.37E-3
0.28 & 3.63E-3 & 4.55E-3
0.36 & 3.99E-3 & 4.19E-3
0.49 & 3.75E-3 & 3.52E-3

<x> & db1 Stat & db1 Sys
0.16 & 3.07E-3 & 5.41E-3
0.28 & 2.54E-3 & 3.19E-3
0.36 & 1.84E-3 & 1.93E-3
0.49 & 8.45E-4 & 7.94E-4

Take care,
Ellie

The 6E-4 came from an older version of your note which stated "Using the values present here for each component that can contribute to the drift we obtain a value no larger than 6×10−4 in Azz."

This has since been clarified (and reduced) as "Using the values presented here for each component that can contribute to the drift we obtain a value no larger than 4.0 × 10−4 in δξ of Eq. 1"

Take care,
Ellie

Hi,
still not sure where the 6x10^-4 came from for pg.22,32, thats not my
number if you got is somewhere else and want to use it ok but still on
pg. 22 the degree of False Asymmetries come from table on pg. 31.
