Hi Oscar,<br>
<br>
I modified this eq as you suggested to show the explicit dependence on Q<br>
and e.<br>

Hi,<br>
<br>
To further remove any confusion about our method and its errors, I suggest<br>
that instead of writing eq. (19) in terms of charge normalized, efficiency<br>
corrected counts, we display the charges and efficiencies explicitly, and<br>
use raw counts. Although we stated the kind of counts we are using in that<br>
eq. just above it, it seems Steve missed it.<br>
<br>
Per eqs. (32) and (33) in the appendix 2.2.3, this means just moving Q's<br>
and<br>
epsilons to the l.h.sides, since N1 and N are indeed raw counts there, and<br>
don't make any approximations, like Q1 ~ Q, etc.<br>
<br>
Then, the l.h.s. of eq. (34) would be<br>
<br>
(Q/Q1)*(e/e1)*(N1/N) and<br>
<br>
eq. (19) becomes<br>
<br>
Azz = 2/(f*Pzz)*[(Q/Q1)*(e/e1)*(N1/<u></u>N) - 1]<br>
<br>
where it's evident that Q's and e's are normalizations or scale factors,<br>
just like f and Pzz, and change the text above the equation to say raw<br>
counts, not normalized and corrected ones.<br>
<br>
I don't see any other way to make it any clearer.<br>
<br>
And, of course, we need to emphasize somewhere that the statistical error<br>
is<br>
always based on the RAW counts.<br>
<br>
Cheers,<br>
<br>

Hi all,<br>
<br>
I got a ton of comments, and I think I've implemented them all. I think<br>
the most substantial pertain to the following: (equation numbers refer to<br>
the attached draft)<br>
<br>
Eq 17 and 19: Azz expressed as ratio - 1 as suggested by Oscar<br>
<br>
Eq 22 : Total time expressed in terms of R_T as noted by Patricia and<br>
concurred by Ellie and Oscar.<br>
<br>
Page 23 Charge determination systematic : modified to reflect Oscar and<br>
JP's suggestions<br>
<br>
There were a lot more, so please double check that your suggestions have<br>
been satisfactorily included.<br>
<br>
The overhead and target sections are still in progress. Anyone have time<br>
to help with that?<br>
<br>
thanks,<br>
<br>
Karl<br>
