We thank the referee for the clear and succinct report.  We have made
the following changes to address the reviewer's comments:

First, rather than a flowchart as such, we have added Table 1 to list
the sequence of detrending steps in their correct order, the IPP stage
in which they are run, and the section number where they are
discussed.

Second, we have added Figure 16 illustrating the sequence of warping
and stacking along with an illustration showing how the chips in the
camera relate to the skycells in the tessellation.

In addition, we have made the following modifications for clarify:

We have also realized that sections 3.7 & 3.11 had some overlapping
content about the background subtractoin. We have moved section 3.7 to
3.10 to place the related discussions together and modified the
wording in section 3.11 to remove duplicative text and instead to
focus on the impact of the background subtraction on large
astrophysical features.  The name of section 3.11 has also been
correspondingly been changed from "Background (``Sky'') Subtraction"
to "Astrophysical vs Other Backgrounds".

As a consequence, sections 3.8,3.9,3.10 have now become 3.7,3.8,3.9.  

Finally, at the urging of a referee of one of the other papers, we
have reduced the number of differnt type faces used for different
concepts and added a description of this usage at the end of Section
1.
