FIXED

> line 75 - 2% for momentum resolution is too high, according to CLAS NIM
> paper it is ~1%
THIS is for z=0: we had z=-55 cm plus 5T, and 2250 A, all making
resolution worse than in NIM paper

> line 77 - the azimuthal angle resolution is 4 mrad, not 3
FIXED

> line 89 - the max current for torus is 3840A
FIXED

> line 101 - too many "the" before "subject" FIXED

> line 107 & 108 - these two sentences has nothing to do with data

> line 133 - "67&" must be corrected, this probably should be 0.27 or 27%
FIXED

> line 144 - why this requirement of 0.3 GeV for neutrons? did you really
> cut this high in energy? YES. The reason for the requirement is that
the skim files had all lower energies cut away for some reason, and
I could not re-make the skim files.

improvement in chi2 when resonances are included for the non exclusive
case. For exclusive case, error bars much bigger so resonances don't show
up very clearly, and too many parameters makes fit 'run away".

FIXED

> line 390 - "From 6" means Eq.(6), so it should be "From Eq.(6)"
FIXED

> line 393 - missing period at the end FIXED

> line 413 - should it be "electron-proton missing mass" ? instead of
> "electron-pion" IT IS CORRECT AS WRITTEN (distinguishes
M from M + Mpi).

> line 427 - just want to make sure that the text files will be attached to
> this paper YES, for arxiv. Will adjust for PRC.

> line 429 - the first 3 sentence, at least, of this paragraph should be
> under "Results", section V, not under V.A FIXED

> line 443 - should be Q^2 FIXED

> line 446 - "fits ARE not bad ..." and "but are considerably ..."
