Dear colleagues,
please few comments/questions from my side (and I'd appreciate if the
next iteration of the draft had line numbers):
p.2: "lepton sign" -> "lepton charge sign"
p.2: -> "passed through unpolarized internal gas target" ("windowless"
is misleading; indeed it had side windows);
p.2: -> "low-energy electrons from Moeller and Bhabha scattering"
p.3: few missing items in tab.1 were mentioned already; other issues:
- what about trigger efficiency?;
- also different choice of rad.corrections is not considered as syst.error?;
- it would probably make sense to break down this table in
correlated and uncorrelated ones explicitely;
- what is the meaning of [0.04-0.13] range for beam energy contribution?;
- I was under impression, that LR-discrepancy was much bigger,
than 0.25%; the plot which Axel showed last time is based on
all 4 analyses?;
I have a feeling it is confusing to quote errors in % in tab.1 and
fig.2, and in absolute units in tab.2 .
MIE method description can be done better. I'd at least mention, that we
are taking about ep-elastic events in the same SYMB acceptance.
Up to 6% rad.correction effect in fig.2 means exactly what? That
uncorrected ratio at low epsilon would be off by 6% away from ~1.00 or
that e+ and e- rates are affected by this amount in a roughly correlated
fashion?
Best regards,
Alexander.
