The Effects of Elemental Abundances on Fitting Supernova Remnant Models to Data

Round 1

Reviewer 1 Report

Report on the paper of D.Leahy "The effect of elemental 
abundances on fitting supernova remnant models to data"

The author describes the modifications used in the standard X-ray modeling program  
XSPEC designed to calculate the supernova remnant (SNR) evolution and to 
obtain the emission measure and electron temperature 
of the gas shocked at forward and reverse shocks.  The modifications include the chemical 
 composition, ionization state, and electron-ion temperature ratio 
and make the modeling more realistic. It is expected that this will  help to compare the 
results of the modeling and X-ray observations of real SNRs.

The results of the paper sound reasonable. However it would be nice if the author add 
 some short results and figures obtained for SNR to illustrate the impact of the 
new elements. 

That is why I recommend a publication after a minor revision. 

Author Response

Author response to reviewer 1:
The request is to add some short results and figures obtained for SNR to illustrate the impact of the new modeling. I chose to use SNR J0049-7314  (from Leahy & Filipovic, 2022) which has reverse shock EM and kT detected, for which the current work is meant to be applied, and added the results in new section 3.4 and Table 3.

Reviewer 2 Report

The results of this paper will be useful for people conducting X-ray analysis of supernova remnants.

The paper is well written, and I have no comments to the text.

I do ask that the author to post the paper on the arXiv (astro-ph) and the journal to accept the paper only after one week on the arXiv, to allow the community to give comments.

Author Response

Author response to reviewer 2: 
I uploaded the paper to www.preprints.org as requested by MDPI. If I should also upload to arXiv, please let me know and I will do that.
