Anthony (4/24):

in data, the electrons were selected via 0<nSigE<3, R<0.02. For pt<5, we fit to 0<adc<303. For pt>5, 303<adc<1000.

In embedding, the only selections are the p range, R<0.02, and eleAcceptTrack. The embedding pt distro was reweighted to match the data.

Anthony (4/5): Added new Raa plot with comparison to strickland's supression models

Anthony (4/4): I attached some dAu cross section plots on this page. The eps versions are on nuclear. The cross sections are as follows:

all: 25.9±4.0 nb

0-2: 1.8±1.7 nb

2-4: 10.9±2.9 nb

4-6. 5.2±5.3 nb

6-8: 0.57±0.59 nb

I expect the cross sections to change once I get new efficiences from embedding, but not by a whole lot.

Drew (4/6): Got Kurt's new lineshapes, efficiencies, and double-ERF parameters today. Uploading the fits to them. I'm not sure I believe the fits...

Bin-by-Bin Counting Cross Section by pT (GeV/c):

|y|<1.0 all: 134.6 ± 10.6 pb

0-2: 27.6 ± 6.3 pb
2-4: 39.1 ± 5.8 pb
4-6: 19.9 ± 3.8 pb
6-8: 13.6 ± 5.1 pb

|y|<0.5 all: 119.2 ± 12.4 pb

0-2: 23.8 ± 6.8 pb
2-4: 35.9 ± 7.4 pb
4-6: 19.0 ± 4.5 pb
6-8: 14.2 ± 4.6 pb

The double ERF is a turn-off from the L2 trigger's mass cut. Kurt used the form: ( {erf*[(m-p1)/p2]+1}*{erf*[(p3-m)/p4]+1} )/2, but I used /4 in the actual fit because each ERF can be at most 2. By fits are also half a bin shifted from Tony's, we'll need to agree on it at some point. The |y|<1 are divided by 2 units in rapidity, and the |y|<0.5 by 1 unit.
