Reviewer 2 Report
This short paper describes a theoretical model for the spectral line shape of Lyman-alpha including Stark broadening in the presence of a strong magnetic field. Theoretical backgrounds of the analytical model and the computer simulation are described in sections 2 and 3, respectively, based largely on the previous publications. The analytical model demonstrates different magnetic-field dependence of Stark broadening for the central and the lateral Zeeman components. Finally the author shows good agreements between the analytical model and the computer simulation for the central Zeeman component under two representative plasma conditions.
The reviewer acknowledges that the paper is clearly described and provide useful information for the analysis of spectral line shape in fusion or astrophysical plasmas. Therefore, the reviewer judges that the paper is acceptable in its present form. To help easier understanding for general readers, the reviewer recommends adding explanations of symbol L (line shape) in equations 5-7 and R (real part) in equation 7 when they first appear.
Author Response
As suggested by the reviewer, explanations of the symbols L (line shape) and \Re (the real part) were added.
Reviewer 3 Report
This paper presents an interesting analytical expression for the p component of the Zeeman triplet is derived for the Stark broadening of Lyman-a for hydrogen-like atoms in a strong magnetic field, which reproduces the feature that the broadening of the p component is independent of the magnetic field and compares well with numerical calculations. Therefore, this study suggests the possibility of using the Stark broadening of the p component for plasma electron density diagnostics. To further emphasize the importance of this study, I would like to propose to add data showing the electron density dependence of the Stark broadening. I hope that the author answers attached comments and questions and improve the manuscript before published in Atoms.

Author Response
- Title - I believe adding "analytical" is unnecessary; it is quite obvious that the manuscript is theoretical.
- I agree about the \sigma -> s index replacement.
- Added such a comparison (Fig. 4).
Round 2
Reviewer 3 Report
The author has adequately addressed reviewer's suggestions for improving understandability and completeness of the manuscript. I recommend this manuscript for publication in Atoms without further review.
