Reviewer 2 Report
This is mainly a review article on opacity, with a few suggestions of improvement over existing calculations, namely calling the reader's attention to the advantages of R-matrix opacity calculations over existing DW data. Although very scarce new results are presented, in my opinion the author's arguments deserve to be published in "Atoms". A few points need clarification and/or correction: 1. The sentence involving Eq. (3) "Direct photoionization ... Eq. (3) for the background cross section" should be rephrased. I believe the author pretends to state that the background cross section is connected to the continuum. In fact the equation for the PI (e+ion) is given, as a description. 2. The word "values" should be added to after "A large number of photoionization cross section" in line 37. 3. In line 39, remove "the" 4. The quantity "S" in Eq. (5) should be identified as the matrix element just mentioned (in the unnumbered line just after line 48). Maybe including "S=" before the matrix element. 5. In Eq. (6) C_j and Phi_j are not identified. 6. In line 59 remove #channel labeled". 7. In line 174, RM refers, I believe, to R-matrix, but is not defined as such. Why not continue using "R-matrix" instead? 8. In line 272, replace "cc" by "cm^-3". 9. In line 287, "??" should be replaced by the correct figure number. 10. The sentences in lines 316-318 should be corrected. 11. In line 322 there is a double "the". 12. In line 333, replace "Fexvii" by "FeXVII" 13. In line 341 replace "calculations, and discussed... " by "calculations are discussed... "Author Response
Thanks for the report. All changes specified by the reviewer have been made in the revised manuscript. The response to one query in the report is as follows. The abbreviation RM for R-matrix is used since the word is used repeatedly and often, particularly in comparison with the Distorted Wave method abbreviated as DW.
