Dear Authors
Thank you for responses and re-submission of the manuscript.
Your responses did not answer one of the major concerns expressed by one of the reviewers, namely the recommendation to change the reference temperature. The concern is with the methods and the outcome of the change. The reviewer was not convinced that it will reduce the uncertainty of the temperature correction. Therefore, I requested two more reviews and received similar concerns about the methods for calculation of uncertainties in temperature fit and respective conclusions. Please see reports of the three additional reviews (attached) and please respond with information requested by reviewers, which will help to make a decision on publication of the paper. Looking forward to your responses.

Dear Authors,
Thank you for submitting responses to comments from three reviewers. The discussion of results was significantly improved. Based on modifications to the manuscript, I made a decision to accept the paper for publication.

The manuscript text still has many grammatical errors.
For example in lines 8 and 9 of the abstract, the following sentence was edited, but now the meaning of what you are trying to say is lost.
"The results clearly show that the traditional methodology based on the internal halogen lamps is not affected by possible temperature affecting the light source". Is it better to say "The results clearly show that the traditional methodology based on the internal halogen lamps is not sensitive to the temperature-caused changes in the spectrum of the light source"? Is it external or internal light source? Please add to. the sentence
P.1 ,line 17, it is installed "IN" the wide range...
P. 2, line 3, suggestion to change to "Preventing mistakes in the wavelength selection are of importance...."
p. 2 line 6 "(?)" - was it a placeholder for the reference to a paper?
p. 2 line 13, (?) - please remove.

There are several places in the text when the sentence ends with "(?)". Please remove or add reference if it is missing.
p. 6, line 19 Not sure what you mean by "verify Equation (5)" Do you mean "confirm to the condition described by Equation (5)"?
p. 7 line 9 suggestion to change to "...for the experiments, sensitivity study was performed."
p. 10, line 19 "relative" -> "relative coefficient "? Not clear what you are saying here. Please clarify.
p. 10 , line 22 - "are" - > "is" , i.e. "the summary is shown"
p. 11, line 17, "show" -> "found"
p. 11, lines 22-23. This sentence is unfinished.
p. 13, line 7-8, another use of "verify Equation (5)". May be "satisfies the conditions defined by Equation (5)"? Please re-write this and next sentence.
p. 13, line 9 -should be "is done"

Please read the manuscript carefully after finalizing the edits and correct text with proper English. You might need to find the native English speaker to proof read your manuscript before the re-submission of the manuscript.
The paper should be resubmitted after the technical corrections are done.
Thank you for the valuable contribution to the special issue.
Regards,
