+
+Please find attached a revised version of the manuscript entitled 
+{\it "A Density-Based Basis-Set Correction For Wave Function Theory"}.
+
+We would to thank the reviewers for their constructive comments.
+Our detailed responses to their comments can be found below.
+For convenience, all modifications and changes are highlighted in red in the revised version of the manuscript. 
+We hope that you will agree that our manuscript is now suitable for publication in JPCL.
+
+We look forward to hearing from you.
+
+\closing{Sincerely, the authors.}

+\noindent \textbf{\large Authors' answer to Reviewer \#1}
+
+\begin{enumerate}
+	\item 
+	\textit{This manuscript reports a major advance in electronic structure theory, by providing a cheap and mathematically motivated correction for finite basis size effects in high-level theories. I expect it to have immediate applications among users, certainly once user friendly code is released. The work is definitely worthy of being published in JPCL, after changes. That said, for the reasons explained below, I think the current manuscript requires changes somewhere between major and minor.}

+\noindent \textbf{\large Authors' answer to Reviewer \#2}
+
+	\textit{This is an excellent paper on density-based basis-set corrections for accelerating the basis-set convergence of an arbitrary wavefunction method. 
+	The corrections are examined for the atomization and correlation energies of the G2 set of molecules. 
+	In wavefunction theory, F12 methods have been developed in the 2000s. 
+	The approach described in this paper provides a fast alternative to F12 that requires relatively large auxiliary basis functions for computing three- and four-electron integrals. 
+	As a small notice, I suggest the the following for an update of reviews on F12, Grueneis et al., J. Chem. Phys., 146, 080901 (2017), Ma and Werner, WIREs Comput. Mol. Sci., 8:e1371 (2018).
+	To summarize, I think this is an excellent paper that should be published in JPCL basically in the present form.}
+
+	\alert{We would like to thank the reviewer for his/her kinds comments.
+	We have added the two references suggested by the reviewer in due place.}
