+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.
