Dear Dr. Dutta,

The above manuscript has been reviewed by one of our referees. Comments
from the report appear below.

These comments suggest that considerable revision of your manuscript is
in order. When you resubmit your manuscript, please include a summary
of any changes made and a succinct response to all recommendations or
criticisms contained in the report.

Yours sincerely,

PROBLEMS WITH MANUSCRIPT:

In reviewing the figures of your paper, we note that the following
changes would be needed in order for your figures to conform to the
style of the Physical Review.  Please check all figures for the
following problems and make appropriate changes in the text of the
paper itself wherever needed for consistency.

Figure(s) [please check all and amend where necessary]
          The lettering in the axis labels and/or numbering size should be
          increased. Please ensure that all lettering is 2 mm or larger
          (1.5 mm for superscripts and subscripts) after scaling to the
          final publication size. Note that the column width is 8.6 cm
          (twice that amount plus gutter for extra wide figures).

Figure(s) [8, 9]
          Please use lower case for consistency: '(arb. units)'

Figure(s) [10]
          Please put units in parentheses following the quantities
          plotted.

Figure(s) [14]
          Please change "CM" to "c.m." (note, lower case, periods).

Figure(s) [14]
          Please add parentheses to factors containing fractions. Please
          note that '1/a b' denotes '1/(a b)'.

Please use regular font, not italic font, in the figure captions.
Please use only standard REVTeX4 coding. Please keep in mind that any
manual intervention, e.g., to remove style modifications, carries the
risk of inadvertently introducing mistakes in the production process.

Similarly, please use standard style and REVTeX4 coding for all tables.

Please consult a recent issue of Physical Review C regarding the preferred
style (e.g., roman font for cheminal element symbols, no vertical column
dividers, captions above tabular material).

Report of the Referee -- CH10189/Qian
----------------------------------------------------------------------

The paper reports on a survey of the pion electroproduction process
over a wide kinematical regime and from a broad variety of targets.
These results have previously been published in PRL 99, 242502 (2007).
The present manuscript is intended as an archival publication, but
does not do the results the justice they deserve, neither in the
relevant details presented nor in the very poor quality of the text.
In its present form listing all the grammatical and textual
shortcomings will take too much time. I urge the collaboration to have
at least one of the co-authors with a good command of the English
language read the manuscript in great detail. The results do merit
publication in Phys Rev C, but not in its present form. Addressing the
issues will require significant modifications before the manuscript
can be reconsidered for publication. Here, I suffice with detailed
comments on the presentation:

1. The summary figure of this paper is #19 in which the parameter
\alpha clearly follow the Q2-dependence of CT predictions. However,
the transparency data shown in fig. 15 are much less convincing. It is
therefore essential that the procedure in determining \alpha together
with the fit quality and the error evaluation is described in fine
detail.

2. The properties of the PLC (and its assumptions) should be explained
in more detail on page 5.

3. The explanation on p. 6 why there is no coherence length dependence
is unclear.

4. Include a ref. for outing CT into the context of QCD factorization
(p. 6).

5. Ref. 7 does not refer to GPDs, thus this reference on p. 6 is
misplaced or wrong.

6. Provide a definition of x_B, prior to p. 6.

7. I assume that raster corrections were applied to the trajectories,
but there is no mention of that in the text (p. 11?).

8. On p. 15 the cell-wall subtraction procedure is described. I assume
that the thickness of the dummy target was chosen to be seven larger
than that of the cell windows to equalize multiple scattering
contributions. If indeed so, mention this in the text.

9. On p. 17 several comments. How was off-shellness tested? The
explanation of the uncorrelated error in radiative corrections is not
clear, nor is how SIMC incorporates pion decay. What is the relation
to Pauli blocking and the distribution function of Fantoni? The FSI
contributions from the knocked-neutron are not explained clearly.

10. On p. 19 the bin-centering procedure should be defined, also in
relation to the averaged values mentioned on p. 21.

11. Somewhere on p. 25 it should be cautioned that the error bars in
sigma_L/sigma_T are 50% or larger.

12. Yerevan is listed twice (footnotes #6 and 19) on the author list.

13. Why is support from FOM and KOSEF acknowledged, when no author is
affiliated with a Dutch or South-Korean institute?

14. Lines and symbols on most figures need to be thickened/enlarged.
